Since we are using vfs_busy() on a freshly allocated mount structure, use
(void) to show that we do not care about the return value.

ipq_zone, to allocate fragment headers from, rather than using cast mbuf
storage. This was one of the few remaining uses of mbuf storage for
local data structures that relied on dtom(). Implement the resource
limit on ipq's using UMA zone limits, but preserve current sysctl
semantics using a sysctl proc.

same behavior to be controlled by the sysctls, hw.syscons.kbd_kbdkey
and hw.syscons.kbd_reboot respectively.
Apologies to the submitter for taking so long to commit this simple
change.

an application to upon a tape (yea, even the non-control device) even if
it cannot establish a mount session. If the open cannot establish a mount
session and O_NONBLOCK was specified, the tape becomes 'open pending mount'.
All I/O operations that would require access to a tape thereafter until
a close attempt to initiate the mount session. If the mount session succeeds,
the tape driver transitions to full open state, else returns an appropriate
I/O error (ENXIO).
At the same time, add a change that remembers whether tape is being opened
read-only. If so, disallow 'write' operations like writing filemarks that
bypass the normal read-only filtering operations that happen in the write(2)
syscall.

was originally meant to handle is not clear -- it's been this way
(broken) since at least RELENG_4.

restored when its removed from the bridge.
At the moment we only clear IFCAP_TXCSUM. Since a locally generated packet on
the bridge may be sent out any one or more interfaces it cant be assumed that
every card does hardware csums. Most bridges don't generate a lot of traffic
themselves so turning off offloading won't hurt, bridged packets are
unaffected.

taskqueue_start_threads(struct taskqueue **, int count, int pri,
const char *name, ...);
This allows the creation of 1 or more threads that will service a single
taskqueue. Also rework the taskqueue_create() API to remove the API change
that was introduced a while back. Creating a taskqueue doesn't rely on
the presence of a process structure, and the proc mechanics are much better
encapsulated in taskqueue_start_threads(). Also clean up the
taskqueue_terminate() and taskqueue_free() functions to safely drain
pending tasks and remove all associated threads.
The TASKQUEUE_DEFINE and TASKQUEUE_DEFINE_THREAD macros have been changed
to use the new API, but drivers compiled against the old definitions will
still work. Thus, recompiling drivers is not a strict requirement.
