Just because an entry is found in the untagged table doesn't

the SCB (return it to the disconnected list or free it), and snoop
for a tag message. Before this change, we reported an unsolicited
reselection. This bug was introduced about a month ago during an
overly aggressive optimization pass on the reselection code.
When cleaning up an SCB, we can't just blindly free the SCB. In
the paging case, if the SCB came off of the disconnected list, its
state may never have been updated in host memory. So, check the
disconnected bit in SCB_CONTROL and return the SCB to the disconnected
list if appropriate.

When aio_read/write() is used on a raw device, physical buffers are
used for up to "vfs.aio.max_buf_aio" of the requests. If a request
size is MAXPHYS, but the request base isn't page aligned, vmapbuf()
will map the end of the user space buffer into the start of the kva
allocated for the next physical buffer. Don't use a physical buffer
in this case. (This change addresses problem report 25617.)
When an aio_read/write() on a raw device has completed, timeout() is
used to schedule a signal to the process. Thus, the reporting is
delayed up to 10 ms (assuming hz is 100). The process might have
terminated in the meantime, causing a trap 12 when attempting to
deliver the signal. Thus, the timeout must be cancelled when removing
the job.
aio jobs in state JOBST_JOBQGLOBAL should be removed from the
kaio_jobqueue list during process rundown.
During process rundown, some aio jobs might move from one list to a
different list that has already been "emptied", causing the rundown to
be incomplete. Retry the rundown.
A call to BUF_KERNPROC() is needed after obtaining a physical buffer
to disassociate the lock from the running process since it can return
to userland without releasing that lock.

Warner gave a nice followup in email, and I thought it would be nice to
get it in the CVS logs. This pertains to rev 1.30 (and the MFC of it):
Space optimization forces the kernel to always use fragments to store
parts of file, rather than using an entire block when less than an
entire block has been written. This forces files to be as small as
they can be at the minor cost of time to do all the fussy stuff. The
cpio image that we put on the disk was so close to filling the disk
exactly that this minor minor difference made a big difference. The
system changed things to time optmization on the first write. When
the end of file was hit, it tried to allocate a full block (4k), but
there was only 3k left on the disk (since you get only 1407 blocks on
a 1.44 floppy) so it failed. So this change nails the space
optmiziation in place for the whole operation.
Make it possible to use IP_TTL and IP_TOS setsockopt(2) options
on certain types of SOCK_RAW sockets. Also, use the ip.ttl MIB
variable instead of MAXTTL constant as the default time-to-live
value for outgoing IP packets all over the place, as we already
do this for TCP and UDP.
