simple-lock.
The reviewer raises the following caveat: "I believe these changes
open a non-critical race condition when adding memory to the pool
for the zone. I think what will happen is that you could have two
threads that are simultaneously adding additional memory when the
pool runs out. This appears to not be a problem, however, since
the re-aquisition of the lock will protect the list pointers."
The submitter agrees that the race is non-critical, and points out
that it already existed for the non-SMP case. He suggests that
perhaps a sleep lock (using the lock manager) should be used to
close that race. This might be worth revisiting after 3.0 is
released.

a similar treatment, and many more that should be converted to plain

command on drives that don't like it. Right now, there's just a bogus
quirk entry in the table that doesn't do anything, but that should be
changed once we get actual inquiry data for drives that don't like the
synchronize cache command.
Also, add a shutdown hook that runs through all direct access peripherals
and runs a synchronize cache on them if they're still open, and if
synchronize cache isn't disabled via a quirk entry.
Add a synchronize cache call at the end of dadump() (again, conditionalized
on the quirk entry), so we can insure that the disk cache contents get
flushed to physical media after a dump.
Check the new quirk entry in daclose() to decide whether or not to
synchronize the cache for a disk at final close.

well) Among them:
[ cd driver ]
1. Old labeling code was still there.
2. Error handling for dsopen() was broken (no test for the `error'
returned by dsopen(); bogus test of an `error' that is known to be 0).
3. cdopen() closed the physical device after certain errors although there
may still be open partitions on it.
4. cdclose() closed the physical device although there may still be open
partitions on it.
5. Some printf format fixes was incomplete or missing.
6. cdioctl() truncated unit numbers mod 256.
7. cdioctl() was missing locking.
[ da driver ]
1. daclose() closed the physical device although there may still be open
partitions on it. This was fixed many years ago in sd.c rev.1.57.
2. A minor optimization (the dk_slices != NULL test) in sdopen() became
uglier in daopen(). It is not worth doing. da only regressed compared
with od and my version of sd, since I never committed the change to sd.
daopen() should probably do less if some partition is already open.
This is not addressed by the diffs.

work with devfs yet. (ask bde for details on this)
- Cleaned up the probe code in both drivers in the failure cases. There
were a number of things wrong here. The peripheral driver instances
weren't getting properly cleaned up. Sometimes the wrong probe message
would get printed out (with the failure message appended), so it wasn't
very clear that we failed to attach. SCSI sense information was printed,
even when the error in question wasn't a SCSI error. I put similar fixes
into the changer driver in revision 1.2 of scsi_ch.c.

FreeBSD repository version of this file and the isdn4bsd version,
adopt those changes from the i4b version that make this file
BSD-version independent. I attempted to avoid uglifying this file too
much, thus deviated a little from the i4b version (and hope they will
adopt the changes, too).
The diffs mostly concentrate on:
. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in
Net/OpenBSD (for loopback detection ad CHAP challenges -- i
assume at least OpenBSD could also benefit from random(), but that's
the way i've got this file)
. interface address list elements are named a little differently
between FreeBSD and Net/OpenBSD
I attempted to segregate those compat fixes from other code fixes and
enhancements.

NFS_ROOT will produce kernel that cannot mount a UFS /.
Vfs type numbers must be distinct from VFS_GENERIC (and VFS_VFSCONF, but
that has the same value and should go away).
The problem happens because NFS is the first vfs (in sys/conf order) so it
gets type number 0 and conflicts harmfully with VFS_GENERIC which is also 0.
The conflict is apparently harmless in the usual case when another vfs
gets type number 0, because nfs is the only vfs that has sysctls.

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.

B_DIRTY buffers are still written too late, as broken in the previous

bitmap buffers and fsck.ext2 can fix up the bitmaps perfectly.
