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.

to spec_vnode_ops. From Bill Studenmund.

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.
(Why this isn't done in ffs_sbupdate(), I dunno...)
