:I'll gladly test them.  I'm in the process of upgrading the lab I run to 3.1
:and it depends heavily on NFS.  Since the lab is closed during finals I won't
:be losing massive amounts of data if they go wrong.  Send 'em on. :)  NFS is a
:big deal to a lot of us, and we'd like to see the changes MFC'd to -stable if
:possible.

    The only major bugfixes that have not been backported from -current to 
    -stable in regards to NFS are the NFS/TCP fix, which is being backported 
    now, and a number of fixes to the VM system when dealing with mmap(), 
    which cannot be backported until we backport the entire -current VM system.
    Also, NFS-stable will break if directories are VMIO'd due to breakage
    in the reconstitution of the valid range ( but directories are not VMIO'd
    in either -stable or -current yet so this will not effect us yet ).  

    The mmap() breakage is unavoidable in -stable but hopefully will not cause
    serious problems for people.  The breakage is related to garbarge showing
    up in the mmap()'d pages *after* the logical file EOF.  That is, if you
    have a 500 byte file and mmap() it into a 4K page, data occuring after
    offset 500 may or may not be 0.

    There are still various other bugs relating to deadlock situations that 
    haven't been fixed in either release that are still being tracked down.
    Fewer then in prior releases, but still present.

:Do you know if they have test patches for -stable as well?  Thanks.

    I would wait until we get the NFS/TCP fix committed to -stable.  It
    should be committed very soon now.
