61a6479ab1 Patch from Kirk McKusick to fix an ordering problem in softdep_setup_freeblks() 
that could cause an inode to be reused prematurely (possibly resulting in the
file containing garbage blocks).

7c2b9d8515 In addition to setting the softdep flag in the superblock when

so that a leftover setting after a crash will be cleared.

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.

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.

861369604d change vfs.ffs.doreallocblks to 1 by default - this does not have 
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.)

7a4d35b365 In lfs_truncate, don't overcount the real blocks removed from the inode, 
when deallocating a fragment that has not made it to disk yet.

Also, during dirops, give the directory vnode an extra reference in
SET_DIROP, to ensure its continued existence during SET_ENDOP, preventing
a possible NULL-dereference there.

These two changes should close PR #11064.
