check for and/or report I/O errors. The result is that a VFS_SYNC
or VOP_FSYNC called with MNT_WAIT could loop infinitely on ufs in
the presence of a hard error writing a disk sector or in a filesystem
full condition. This patch ensures that I/O errors will always be
checked and returned. This patch also ensures that every call to
VFS_SYNC or VOP_FSYNC with MNT_WAIT set checks for and takes
appropriate action when an error is returned.

so that KSEs with no mailbox in a KSE program are not a cause
of page faults (this can legitmatly happen).

linked modules, unlike dynamically linked modules, get INVARIANTS,
so if there are INVARIANTS failures, you'll bump into them rather
than not. Add the options to NOTES.

Add code to free KSEs and KSEGRPs on exit.
Sort KSE prototypes in proc.h.
Add the missing kse_exit() syscall.
ksetest now does not leak KSEs and KSEGRPS.

extra function calls. Refactor uma_zalloc_internal into seperate functions
for finding the most appropriate slab, filling buckets, allocating single
items, and pulling items off of slabs. This makes the code significantly
cleaner.
- This also fixes the "Returning an empty bucket." panic that a few people
have seen.

o As a second order fix, don't assume we have enough space
after the bootinfo block left in a page to hold the memory
map.
o A third order fix as that we removed the assumption that a
bootinfo block fits in a single 8KB page.

Unfortunately, this also means that the free checks are not done before

to the primary local IP address when doing a TCP connect(). The
tcp_connect() code was relying on in_pcbconnect (actually in_pcbladdr)
modifying the passed-in sockaddr, and I failed to notice this in
the recent change that added in_pcbconnect_setup(). As a result,
tcp_connect() was ending up using the unmodified sockaddr address
instead of the munged version.
There are two cases to handle: if in_pcbconnect_setup() succeeds,
then the PCB has already been updated with the correct destination
address as we pass it pointers to inp_faddr and inp_fport directly.
If in_pcbconnect_setup() fails due to an existing but dead connection,
then copy the destination address from the old connection.
This policy can be loaded dynamically, and assigns each process a
partition number, as well as permitting processes to operate outside
the partition. Processes contained in a partition can only "see"
processes inside the same partition, so it's a little like jail.
The partition of a user can be set using the label mechanisms in
login.conf. This sample policy is a good starting point for developers
wanting to learn about how to produce labeled policies, as it labels
only one kernel object, the process credential.

- Add detach support to the driver so that you can kldunload the module.
Note that currently rc_detach() fails to detach a unit if any of its
child devices are open, thus a kldunload will fail if any of the tty
devices are currently open.

In order to properly handle reset requests whether they originate in the
ATA layer (atacontrol reinit) or from the CAM layer (camcontrol reset)
ata_reinit does not cause the SIM to be deallocated anymore. The SIM
is now unconditionnally created for each ATAPI bus.
This change may cause existing bus ids to change on some setups.
