The page hold mechanism is fast but it has couple of fallouts:
- It does not let pages respect the LRU policy
- It bloats the active/inactive queues of few pages
Try to avoid it as much as possible with the long-term target to
completely remove it.
Use the soft-busy mechanism to protect page content accesses during
short-term operations (like uiomove_fromphys()).
After this change only vm_fault_quick_hold_pages() is still using the
hold mechanism for page content access.
There is an additional complexity there as the quick path cannot
immediately access the page object to busy the page and the slow path
cannot however busy more than one page a time (to avoid deadlocks).
Fixing such primitive can bring to complete removal of the page hold
mechanism.

Revert r253939:
We cannot busy a page before doing pagefaults.
Infact, it can deadlock against vnode lock, as it tries to vget().
Other functions, right now, have an opposite lock ordering, like
vm_object_sync(), which acquires the vnode lock first and then
sleeps on the busy mechanism.
Before this patch is reinserted we need to break this ordering.

Change CCB queue resize logic to be able safely handle overallocations:
- (re)allocate queue space in power of 2 chunks with 64 elements minimum

- automatically reallocate the queue to double size if it is overflowed.
- if queue reallocation failed, store extra CCBs in unsorted TAILQ,
fetching them back as soon as some queue element is freed.
To free space in CCB for TAILQ linking, change highpowerq from keeping
high-power CCBs to keeping devices frozen due to high-power CCBs.

The tmpfs_alloc_vp() is used to instantiate vnode for the tmpfs node,
in particular, from the tmpfs_lookup VOP method. If LK_NOWAIT is not
specified in the lkflags, the lookup is supposed to return an alive
vnode whenever the underlying node is valid.
Currently, the tmpfs_alloc_vp() returns ENOENT if the vnode attached
to node exists and is being reclaimed. This causes spurious ENOENT
errors from lookup on tmpfs and corresponding random 'No such file'
failures from syscalls working with tmpfs files.
Fix this by waiting for the doomed vnode to be detached from the tmpfs
node if sleepable allocation is requested.
Note that filesystems which use vfs_hash.c, correctly handle the case
due to vfs_hash_get() looping when vget() returns ENOENT for sleepable
requests.

When entering exception handlers we may not have an aligned stack. This is
because an exception may happen at any time. The stack alignment rules on
ARM EABI state the only place the stack must be 8-byte aligned is on a
function boundary.
If an exception happens while a function is setting up or tearing down it's
stack frame it may not be correctly aligned. There is also no requirement
for it to be when the function is a leaf node.
The fix is to align the stack after we have stored a backup of the old stack
pointer, but before we have stored anything in the trapframe. Along with
this we need to adjust the size of the trapframe by 4 bytes to ensure the
stack below it is also correctly aligned.

type occurs without a corresponding record of the other resource
record type. [RT #33355]

Make ZFS to use separate thread to handle SPA_ASYNC_REMOVE async events.
Existing async thread is running only on successfull spa_sync() completion,
that is impossible in case of pool loosing required (last) disk(s). That
indefinite delay of SPA_ASYNC_REMOVE processing made ZFS to not close the
lost disks, preventing GEOM/CAM from destroying devices and reusing names
on later disk reattach.
In earlier version of the patch I've tried to just run existing thread
immediately, unrelated to spa_sync() completion, but that exposed number
of situations where it could stuck due to locks held by stuck spa_sync(),
that are required for other kinds of async events.
Experiments with OpenIndiana snapshot confirmed that they also have this
issue with lost disks reattach.

Disable r252840 when ZFS TRIM is enabled (vfs.zfs.trim.enabled=3D1) and rea=

r252840 (illumos bug 3836) is based on assumption that zio_free_sync() has
no lock dependencies and should complete immediately. Unfortunately, with o=
ur
TRIM implementation that is not true due to ZIO_STAGE_VDEV_IO_START added
to the ZIO_FREE_PIPELINE, which, while not really accessing devices, still
acquires SCL_ZIO lock for read to be sure devices won't disappear.
When TRIM is disabled, this patch enables direct free execution from r252840
and removes ZIO_STAGE_VDEV_IO_START and ZIO_STAGE_VDEV_IO_ASSESS stages from
the pipeline to avoid lock acquisition. Otherwise it queues free request as
it was before r252840.

Block reporting of ZFS features for suspended pools.
Before executing any subcommand, zpool tool fetches pools configuration from
the kernel. Before features support was added, kernel was regenerating that
configuration based on data always present in memory. Unfortunately, pool
features list and activity counters are not such. They are stored in ZAP,
that normally resides in ARC, but under heavy memory pressure may be swapped
out. If pool is suspended at this point, there is no way to recover it back
since any zpool command will stuck.
This change has one predictable flaw: `zpool upgrade` always wish to upgrade
suspended pools, but fortunately it can't do it due to the suspension.

This bug fix is in a code path in rename taken when there is a
collision between a rename and an open system call for the same
target file. Here, rename releases its vnode references, waits for
the open to finish, and then restarts by reacquiring its needed
vnode locks. In this case, rename was unlocking but failing to
release its reference to one of its held vnodes. The effect was
that even after all the actual references to the vnode had gone,
the vnode still showed active references. For files that had been
removed, their space was not reclaimed until the filesystem was
forcibly unmounted.
This bug manifested itself in the Postgres server which would
leak/lose hundreds of files per day amounting to many gigabytes of
disk space. This bug required shutting down Postgres, forcibly
unmounting its filesystem, remounting its filesystem and restarting
Postgres every few days to recover the lost space.

As it turns out, MSIs are broken with 2820SA so introduce an AAC_FLAGS_NOMSI
quirk and apply it to these controllers [1]. The same problem was reported
for 2230S, in which case it wasn't actually clear whether the culprit is the
controller or the mainboard, though. In order to be on the safe side, flag
MSIs as being broken with the latter type of controller as well. Given that
these are the only reports of MSI-related breakage with aac(4) so far and
OSes like OpenSolaris unconditionally employ MSIs for all adapters of this
family, however, it doesn't seem warranted to generally disable the use of
MSIs in aac(4).
While it, simplify the MSI allocation logic a bit; there's no need to check
for the presence of the MSI capability on our own as pci_alloc_msi(9) will

"PC98_" prefix. This way, both <sys/diskmbr.h> and <sys/diskpc98.h>
can be included in the same C source file.
The renaming is trivial. The only gotcha is that DOSBBSECTOR is
also redefined from 0 to 1. This because DOSBBSECTOR was always
used in conjunction with an addition of 1. The PC98_BBSECTOR symbol
is defined as 1 and the expression is simplified.
Note: it is not believed that ports are seriously impacted; or at
all for that matter.

Change the pmap_ts_referenced() method of amd64 pmap to use shared
pvh_global_lock. This allows the method to be executed in parallel,
avoiding undue contention on the pvh_global_lock for the multithreaded
pagedaemon.
The pmap_ts_referenced() function has to inspect the page mappings for
several pmaps, which need to be locked while pv list lock is owned.
This contradicts to the lock order, where pmap lock is before pv list
lock. Introduce the generation count for the pv list of the page or
superpage, which indicate any change in the pv list, and, as usual,
perform restart of the iteration if generation changed while pv lock
was dropped for blocking acquire of a pmap lock.

Split the pagequeues per NUMA domains, and split pageademon process
into threads each processing queue in a single domain. The structure
of the pagedaemons and queues is kept intact, most of the changes come
=66rom the need for code to find an owning page queue for given page,
calculated from the segment containing the page.
The tie between NUMA domain and pagedaemon thread/pagequeue split is
rather arbitrary, the multithreaded daemon could be allowed for the
single-domain machines, or one domain might be split into several page
domains, to further increase concurrency.
Right now, each pagedaemon thread tries to reach the global target,
precalculated at the start of the pass. This is not optimal, since it
could cause excessive page deactivation and freeing. The code should
be changed to re-check the global page deficit state in the loop after
some number of iterations.
The pagedaemons reach the quorum before starting the OOM, since one
thread inability to meet the target is normal for split queues. Only
when all pagedaemons fail to produce enough reusable pages, OOM is
started by single selected thread.
Launder is modified to take into account the segments layout with
regard to the region for which cleaning is performed.

Convert net80211 over to using if_transmit for the dispatch from the

This eliminates the if_snd queue from net80211. Yay!
This unfortunately has a few side effects:
* It breaks ALTQ to net80211 for now - sorry everyone, but fixing
parallelism and eliminating the if_snd queue is more important
than supporting this broken traffic scheduling model. :-)
* There's no VAP and IC flush methods just yet - I think I'll add
some NULL methods for now just as placeholders.
* It reduces throughput a little because now net80211 will drop packets
rather than buffer them if the driver doesn't do its own buffering.
This will be addressed in the future as I implement per-node software
queues.

The soft and hard busy mechanism rely on the vm object lock to work.
Unify the 2 concept into a real, minimal, sxlock where the shared
acquisition represent the soft busy and the exclusive acquisition
represent the hard busy.
The old VPO_WANTED mechanism becames the hard-path for this new lock
and it becomes per-page rather than per-object.
The vm_object lock becames an interlock for this functionality:
it can be held in both read or write mode.
However, if the vm_object lock is held in read mode while acquiring
or releasing the busy state, the thread owner cannot make any
assumption on the busy state unless it is also busying it.
Also:
- Add a new flag to directly shared busy pages while vm_page_alloc
and vm_page_grab are being executed. This will be very helpful
once these functions happen under a read object lock.
- Move the swapping sleep into its own per-object flag
The KPI is heavilly changed this is why the version is bumped.
It is very likely that some VM ports users will need to change
their own code.

* If the kernel doesn't have any random_adaptor adapters present then the
creation of /dev/random is postponed until next random_adaptor is kldload=
'ed.
* Fix randomdev_soft.c to refer to its own random_adaptor, instead of a
system wide one.

Initial commit of my USB test code which can exercise connected USB
devices and the FreeBSD USB stack itself. This program can be used to
test compliance against well established usb.org standards, also
called chapter-9 tests. The host platform can act as either USB device
or USB host depending on the available hardware. The basic USB
communication happens through FreeBSD's own libusb v2, and some
sysctls are also used to invoke specific error conditions. This test
program can be used to verify correct operation of external USB
harddisks under heavy load and various other conditions. The software
is driven via a simple command line interface. Main supported USB host
classes are "USB mass storage" and "USB modems".

Different consumers of the struct vm_page abuse pageq member to keep
additional information, when the page is guaranteed to not belong to a
paging queue. Usually, this results in a lot of type casts which make
reasoning about the code correctness harder.
Sometimes m->object is used instead of pageq, which could cause real
and confusing bugs if non-NULL m->object is leaked. See r141955 and
r253140 for examples.
Change the pageq member into a union containing explicitly-typed
members. Use them instead of type-punning or abusing m->object in x86
pmaps, uma and vm_page_alloc_contig().

Change i_gen in UFS to an unsigned type.
In UFS, i_gen is a random generated value and there is not way for

match bit patterns and it is of no consequence if the values are
signed or not. Following other filesystems, set it to unsigned,
Calculation for older filesystems remains untouched.

As it turns out, MSIs are broken with 2820SA so introduce an AAC_FLAGS_NOMSI
quirk and apply it to these controllers [1]. The same problem was reported
for 2230S, in which case it wasn't actually clear whether the culprit is the
controller or the mainboard, though. In order to be on the safe side, flag
MSIs as being broken with the latter type of controller as well. Given that
these are the only reports of MSI-related breakage with aac(4) so far and
OSes like OpenSolaris unconditionally employ MSIs for all adapters of this
family, however, it doesn't seem warranted to generally disable the use of
MSIs in aac(4).
While at it, simplify the MSI allocation logic a bit; there's no need to
check for the presence of the MSI capability on our own as pci_alloc_msi(9)
will just fail when these kind of interrupts are not available.

- Implement iclear methods for QUICC and SAB 82532. With r253161 in place,
this is is crucial at least for the latter.
What happens is that attaching uart(4) to scc(4) causes the SAB 82532 to
"receive" something and trigger a SER_INT_RXREADY interrupt, given that
at least fast/filter interrupts are already enabled. Prior to r253161,
uart_bus_ihand() was set up at this point and handled that condition,
i. e. read the RX FIFO and issued a Receive Message Complete.
Now, uart_bus_ihand() and uart_intr() are setup after attaching uart(4),
leaving the SER_INT_RXREADY interrupt triggered during the latter to
be handled by the iclear method. However, with that method not implement,
this in turn causes SAB 82532 to not issue any further SER_INT_RXREADY
interrupts until the RX FIFO is full again. Thus, 15 received bytes go
to nowhere, given that "the other half" of the RX FIFO is used for status
information. Hence, implementing sab82532_bfe_iclear() fixes things again.
Potentially, the same problem exists for QUICC.
- Remove unnecessary __RMAN_RESOURCE_VISIBLE.
- Remove a superfluous header.
- Use KOBJMETHOD_END.
- Mark unused arguments as such.
- Remove variables unused after initialization.

Implementation of the HTree directory index.
This is a port of NetBSD's GSoC 2012 Ext3 HTree directory indexing
by Vyacheslav Matyushin. It was cleaned up and enhanced for FreeBSD
by Zheng Liu (lz@).
This is an excellent example of work shared among different projects:
Vyacheslav was able to look at an early prototype from Zheng Liu who
was also able to check the code from Haiku (with permission).
As in linux, the feature is not available by default and must be
enabled explicitly with tune2fs. We still do not support the
workarounds required in readdir for NFS.
