must be recalculated. The blk_check pass of suj checker explicitely marks
inodes which owned such blocks as needing block count adjustment. But
ino_adjblks() is only called by cg_trunc pass, which is performed before
blk_check. As result, the block use count for such inodes is left wrong.
This causes full fsck run after journaled run to still find inconsistencies
like 'INCORRECT BLOCK COUNT I=14557 (328 should be 0)' in phase 1.
Fix this issue by running additional adj_blk pass after blk_check, which
updates the field.

to resolve errors which can cause corruption on recovery with the old
synchronous mechanism.
- Append partial truncation freework structures to indirdeps while
truncation is proceeding. These prevent new block pointers from
becoming valid until truncation completes and serialize truncations.
- On completion of a partial truncate journal work waits for zeroed
pointers to hit indirects.
- softdep_journal_freeblocks() handles last frag allocation and last
block zeroing.
- vtruncbuf/ffs_page_remove moved into softdep_*_freeblocks() so it
is only implemented in one place.
- Block allocation failure handling moved up one level so it does not
proceed with buf locks held. This permits us to do more extensive
reclaims when filesystem space is exhausted.
- softdep_sync_metadata() is broken into two parts, the first executes
once at the start of ffs_syncvnode() and flushes truncations and
inode dependencies. The second is called on each locked buf. This
eliminates excessive looping and rollbacks.
- Improve the mechanism in process_worklist_item() that handles
acquiring vnode locks for handle_workitem_remove() so that it works
more generally and does not loop excessively over the same worklist
items on each call.
- Don't corrupt directories by zeroing the tail in fsck. This is only
done for regular files.
- Push a fsync complete record for files that need it so the checker
knows a truncation in the journal is no longer valid.

Due to UFS insistence to pretend that device sector size is 512 bytes,
sector size is obtained from ioctl(DIOCGSECTORSIZE) for real devices,
and from the label otherwise. The file images without label have to
be made with 512 sector size.

is accomplished by detecting a directory with no . or .. links and
clearing the named directory entry in the parent.
- Add a new function ino_remref() which handles the details of removing
a reference to an inode as a result of a lost directory. There were
some minor errors in various subcases of this routine.
- Use err/errx only when the case is really fatal. For other
cases, fall back to full fsck instead of quiting fsck.
- Plug a memory leak.
- Avoid divide by zero when printing summary.
- Output "FILE SYSTEM IS MARKED CLEAN" when a successful

- When -f is specified, do full fsck instead of journal recovery.
