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".

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...)

caller's file and line to _malloc and _free.

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.

aby bad symptoms any more, fix for bug causing problems with this
option was in BSD4.4-Lite2 and pulled in together with softdep changes

31fc62d4e9 Correct accounting of lfs_avail, locked_queue_count, and locked_queue_bytes. 
(PR #11468).  In the case of fragment allocation, check to see if enough
space is available before extending a fragment already scheduled for writing.

The locked_queue_* variables indicate the number of buffer headers and bytes,
respectively, that are unavailable to getnewbuf() because they are locked up
waiting for LFS to flush them; make sure that that is actually what we're
counting, i.e., never count malloced buffers, and always use b_bufsize instead
of b_bcount.

If DEBUG is defined, the periodic calls to lfs_countlocked will now complain
if either counter is incorrect.  (In the future lfs_countlocked will not need
to be called at all if DEBUG is not defined.)
