Modified files:
sys/kern vfs_subr.c
sys/miscfs/specfs spec_vnops.c
sys/sys vnode.h
Log:
Move the buffered read/write code out of spec_{read|write} and into
two new functions spec_buf{read|write}.
Add sysctl vfs.bdev_buffered which defaults to 1 == true. This
sysctl can be used to experimentally turn buffered behaviour for
bdevs off. I should not be changed while any blockdevices are
open. Remove the misplaced sysctl vfs.enable_userblk_io.
No other changes in behaviour.
