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).

because the variable is often unset, but this is not always the

they may be statically linked into the kernel. Note that statically
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.

MAC labels are set if MAC is enabled and configured for the user
logging in.
Note that lukemftpd is not considered a supported application when
MAC is enabled, as it does not use the standard system interfaces for
managing user contexts; if lukemftpd is used with labeled MAC policies,
it will not properly give up privileges when switching to the user
account.

* Remove unnecessary cross-references from the SEE ALSO sections of
aio_*(2); config(8), kldload(8) and kldunload(8) are cross-referenced

* Remove the KERNEL OPTIONS sections from aio_*(2), now that these

Add the missing kse_exit() syscall.

for finding the most appropriate slab, filling buckets, allocating single
items, and pulling items off of slabs. This makes the code significantly
cleaner.

o A third order fix as that we removed the assumption that a
bootinfo block fits in a single 8KB page.
