At using tcpdump for cs interface, tcpdump only dump packet which

packet between others.

The problem is caused when a directory block is compacted. When this
occurs, softdep_change_directoryentry_offset() is called to relocate each
directory entry and adjust its matching diradd structure, if any, to match
the new location of the entry. The bug is that while
softdep_change_directoryentry_offset() correctly adjusts the offsets of
the diradd structures on the pd_diraddhd[] lists (which are not yet ready
to be committed to disk), it fails to adjust the offsets of the diradd
structures on the pd_pendinghd list (which are ready to be committed to
disk). This causes the dependency structures to be inconsistent with
the buf contents. Now, if the compaction has moved a directory entry to
the same offset as one of the diradd structures on the pd_pendinghd list
*and* a syscall is done that tries to remove this directory entry before
this directory block has been written to disk (which would empty
pd_pendinghd), a sanity check in newdirrem() will call panic() when it
notices that the inode number in the entry that it is to be removed doesn't
match the inode number in the diradd structure with that offset of that
entry.

an ext2fs file system is mounted. The soft update changes added
a check for B_DELWRI buffers. This exposed the complete brokenness
of the previous quick fix for failing syncs (PR 3571, committed on
1997/08/04). Use a new buffer flag B_DIRTY and don't abuse B_DELWRI.
B_DIRTY buffers are still written too late, as broken in the previous
fix. This is fairly harmless, because B_DIRTY is only used for
bitmap buffers and fsck.ext2 can fix up the bitmaps perfectly.
Fixed a race in ULCK_BUF() (bremfree() was outside of the splbio()
section).

This is a good bit more useful than the other debugging modes, I think.

Save the slice table and disklabel when opening a disk.
Add bd_getdev(), which attempts to return a dev_t corresponding

- The inevitable da-when-wd-also-exists
- Disks with no slice table (the slice number is not set correctly)
The first is difficult to get right, the second will be
fixed in an upcoming commit.
