chs 45701591c6 add a genfs_mmap() and change all of the disk-based filesystems
to implement VOP_MMAP() with the genfs version, in preparation for
actually using this VOP.

enami c17241f92a Don't flush possibilly relocated file system block if write is done
asynchronously.  They will be flushed later when necessary and flushing
now makes sequential write access very slow.

thorpej 5b35dc8136 When unmounting a file system, acquire the syncer_lock before
vfs_busy'ing just before the dounmount() call.  This is to avoid
sleeping with the mountlist_slock held -- but we must acquire
syncer_lock before vfs_busy because the syncer itself uses
syncer_lock -> vfs_busy locking order.

fvdl ad5dcb280f Same change as in the UFS code: unlock vnode before setting v_op
to spec_vnode_ops. From Bill Studenmund.

fvdl 509b0d01a5 Do an explicit VOP_UNLOCK in ufs_vinit before setting v_op to
spec_vnode_ops_p. Workaround for a lock leak. Problem tracked
down by der Mouse.

sommerfeld d02dde9937 Change ffs_dirpref() to pay attention to the amount of available free
space before deciding which cylinder group should contain a new directory
inode.

Fixes kern/11983; works around some, but not all, of the side effects
of kern/11989.

Tested by me for well over a month on my laptop; preliminary versions of
the fix were tested by Frank van der Linden and Herb Peyerl.

fvdl 418264a670 Some bugfixes from rev 1.33 and 1.34 of this file in FreeBSD (some
in effect cosmetic). Original FreeBSD commit messages:

Bug fixes for currently harmless bugs that could rise to bite
the unwary if the code were called in slightly different ways.

[...]

2) In ufs_lookup() there is an off-by-one error in the test that checks
if dp->i_diroff is outside the range of the the current directory size.
This is completely harmless, since the following while-loop condition
'dp->i_offset < endsearch' is never met, so the code immediately
does a second pass starting at dp->i_offset = 0.

3) Again in ufs_lookup(), the condition in a sanity check is wrong
for directories that are longer than one block. This bug means that
the sanity check is only effective for small directories.

    In the 'found' case for ufs_lookup() the underlying bp's data was
    being accessed after the bp had been releaed.  A simple move of the
    brelse() solves the problem.

cgd 4dddddfe62 fix bug (pointed out as sequence point violation warning with current-ish gcc)
caused by use of makedev(major,minor++).  makedev() now (since 32-bit
dev_t conversion) evaluates its second argument twice.

augustss 46ee162100 Fix from chuq:
don't update UVM's notion of the file size before the VOP_FSYNC() when
we're partially truncating a file with softdeps enabled.  doing so could
free pages without updating the dependency info, which would result in
"panic: softdep_write_inodeblock: direct pointer #1 mismatch 0 != N".

mycroft fad85a24d8 On a RW->RO transition, explicitly clear fs_fmod after the cgupdate/sbupdate,
to prevent spurious writebacks and whinging about the (correct!) clean flag.

perseant 2a53ff5ab9 Get rid of some old unnecessary code that cleared B_NEEDCOMMIT from buffers in
lfs_writeseg (possibly after they had been freed).

If MALLOCLOG is defined, make lfs_newbuf and lfs_freebuf pass along the
caller's file and line to _malloc and _free.

chs 6944ee458a in ufs_balloc_range(), don't rely on uvm_vnp_setsize() to invalidate
pages we've allocated past the real EOF when we fail to allocate a block.
we used to play games with the VM notion of the file size but we don't do
that anymore, so uvm_vnp_setsize() doesn't do what we want anymore.
call the pager flush op instead.
