under -current. The actual preparation of the next track will now be
deferred until just before the first write operation. Otherwise,
opening the device with write intent will cause the execution of
commands that are illegal in `limited command set mode' (i.e., after
the write channel has been opened).
While i was at it, cleaned up the worm_open() function a bit.
Removed the volume overflow pre-check in worm_strategy(). It was
time-consuming, and rather useless in many cases anyway (with the size
being reported for just the entire volume only), so we can as well let
the actual SCSI command fail instead, where it'll properly be reported
as EIO.

fix PR#3618 weren't sufficient since malloc() can block - allowing the
net interrupts in and leading to the same problem mentioned in the
PR (a panic). The order of operations has been changed so that this
is no longer a problem.
Needs to be brought into the 2.2.x branch.

of time that the laptop was suspending. Thus, select() calls that might have
suspended rather than firing at 1hr + "time suspended" since the timer was
posted.
Adding:
options APM_FIXUP_CALLTODO
to the kernel config enables the patch.
[
This patch was slightly modified to use a consistant indent style and
I removed some unused local variables. After this has been tested a
few weeks we'll make the options the default, so for now I'm now
documenting it in LINT. Mike can later if he wants.

will be rejected with BUSY.
IMHO, this flag can completely go away for cd9660. There's no reason
you need to prevent CDs from being mounted multiple times, and in case
of multisession CDs it can even make sense to mount two different
sessions by the same time (to different mount points, otherwise it
would be pointless ;).

nevertheless (albeit with a warning), but cannot be opened except of
the SCSI control device (so scsi(8) or cdrecord will continue to
work).
It failed to recognize the PCI bus in a system that had only an
old chip-set (class code 000000) and a Cyclom multiport serial
card on PCI bus 0, but no VGA card or disk or network controller.

flag is set in the p_pfsflags field. This, essentially, prevents an SUID
proram from hanging after being traced. (E.g., "truss /usr/bin/rlogin" would
fail, but leave rlogin in a stopevent state.) Yet another case where procctl
is (hopefully ;)) no longer needed in the general case.

out of bounds a_entry is a kernel and use the usual kludge to find
the text address). If gdb had used this, it would have been able
to find the kernel text address properly. Unfortunately, it uses
its own a.out macros, so this is mainly an example for gdb to copy.
