fvdl ef6bdbccd8 Stay at splbio across the VBWAIT loop, as is done elsewhere in the
kernel. Avoids a possible race condition. Pointed out by
enami@netbsd.org, problem reported by deberg@netbsd.org.

fvdl 81ba8e7ff7 Adapt for VOP_FSYNC parameter change.
Implement range fsync for FFS. Note: not yet implemented for the
SOFTDEP case.

mycroft 4db674fa50 According to Frank, buffers with dependencies *are* left on v_dirtyblks, so
remove the FSYNC_RECLAIM check and force them to be flushed.

mycroft 941524439a Never call softdep_sync_metadata() in the FSYNC_RECLAIM case. Any pending
blocks are detached from the vnode at this point.  When the dependencies are
broken to enable writing the blocks, the vnode will be regenerated.  (The only
reason we sync buffers in this case is that they have to be detached from the
vnode.)

mycroft c47adf55e0 In ffs_fsync(), remove the FSYNC_RECLAIM special case, so that it properly
waits for pending buffers, and doesn't throw away time stamp updates.

perseant f0728fdce1 Change the sementics of the last parameter from a boolean ("waitfor") to
a set of flags ("flags").  Two flags are defined, UPDATE_WAIT and
UPDATE_DIROP.

Under the old semantics, VOP_UPDATE would block if waitfor were set,
under the assumption that directory operations should be done
synchronously.  At least LFS and FFS+softdep do not make this
assumption; FFS+softdep got around the problem by enclosing all relevant
calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply
ignored waitfor, one of the reasons why NFS-serving an LFS filesystem
did not work properly.

Under the new semantics, the UPDATE_DIROP flag is a hint to the
fs-specific update routine that the call comes from a dirop routine, and
should be wait for, or not, accordingly.

Closes PR#8996.

fvdl 563d336e44 Don't immediately return in ffs_fsync if there appears to be no data
to flush if it's a vnode on a softdep filesystem. softdep_sync_metadata
may still need to do some work.

perseant 61fa9e1409 Move vinvalbuf's check for dirty blocks into ffs_fsync, to ensure that
mode and ownership bits are flushed to disk before the vnode is
reclaimed.

The check, introduced in the softdep merge, assumes that if no blocks
are dirty, no file data *or metadata* needs to be flushed to disk.  This
is true of ffs, but is not true of lfs, and may not be true of other
filesystems.

Tested by myself and Bill Squier <groo@cs.stevens-tech.edu>.

fvdl 0b1963121a Add Kirk McKusick's soft updates code to the trunk. Not enabled by
default, as the copyright on the main file (ffs_softdep.c) is such
that is has been put into gnusrc. options SOFTDEP will pull this
in. This code also contains the trickle syncer.

wrstuden 3bf14d81e9 Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl
call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

thorpej 60cfe320cc Use the pool allocator and the "nointr" pool page allocator for FFS inodes.
XXX MFS also comes in here for inodes, and used a different malloc type,
but the structure is the same, so we just use the FFS inode pool.

mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)
