disable interrupts completely, and stxa_sync(), which performs a store
immediately followed by a membar #Sync with interrupts disabled (this
is needed for writes to diagnostic registers).
to multi-volume restores:
- In findinode(), keep a copy of header->c_type so that we don't
exit the do-while loop until we have processed the current header.
Exiting too early leaves curfile.ino set to 0, which confuses
the logic in createfiles(), so multi-volume restores with the
'x' command don't work if you follow the instructions and supply
the tapes in reverse order. This appears to have been broken
by CSRG revision 5.33 tape.c (Oct 1992).
- The logic in getvol() for deciding how many records to skip after
the volume header was confused; sometimes it would skip too few
records and sometimes too many, leading to "resync restore"
warnings and missing files. Skip to the next header only when
the current action is not `USING'. Work around a dump bug that
sets c_count incorrectly in the volume header of the first tape.
Some of the problems here date back to at least 1991.
- Back out revision 1.23. This appeared to avoid warnings about
missing files in the 'rN' verification case, but it made the
problems with the 'x' command worse by stopping getvol() from
even attempting to find the first inode number on the newly
inserted tape. The bug it addressed is fixed by correcting the
skipping logic as described above.
- Save the value of `tpblksread' in case the wrong volume is
supplied, because it is incremented each time we read a volume
header. We already saved `blksread' for the same reson.
slower, and may be impeding adoption of -CURRENT by developers. We
recommend turning on WITNESS by default on crash boxes, and when doing
locking development. It will probably get turned on by default for a week
or two following any major locking commits, also.

I'll know as soon as I re-import it and compile it.. :-)
There is no longer a 'pri' strict in the proc struct.

it.

We ensure that 'ports.tgz' tarball should have ports/distfiles directory.
At first, ${CHROOTDIR}/usr/ports is empty (rm -rf ports), then extract
ports files from CVS repository. Then if RELEASEDISTFILES is defined,
${CHROOTDIR}/usr/ports/distfiles directory is created by cp(1). However,
if you don't specify RELEASEDISTFILES, there is no chance to create
${CHROOTDIR}/usr/ports/distfiles directory.

More cleanups of the RAID1 failure mode code.
Add functionality that writes the changed RAID config setup
back to the disks (in controller BIOS specific format), so
that a reboot will make the BIOS pick up the changed config.
* Fix a problem with files that have no CVS $Id's. Thanks to naddy for
spotting this one. It wasn't a _huge_ problem since almost all the files
we install (except motd) have one, but still, it's a bug.
* Add a divider between diff outputs, which is helpful both for logs,
and for giving a good visual clue for diffs that are smaller than
$LINES. Another helpful suggestion from Gary W. Swearingen, swear@blarg.net.
1) We shouldn't continue when we get a RX complete because we ack it
and the TX complete.
2) Fix a couple of spl leaks
(why splbio is needed in ISR, I cannot understand).
