This flag gets set whenever the thread posts an event on the GEOM
event queue, and if the flag is set when the thread is prepared
to return to userland from the kernel, g_waitidle() will be called
to make sure that the posted events have completed.
This can replace an insufficient number of g_waitidle() calls in
various other places, and has the advantage of being failsafe: Any
system call which does a VOP_OPEN()/VOP_CLOSE will now correctly
wait for any geom events it posted as part of spoils or tastes.
Assert that topology and Giant is not held in g_waitidle().
or pru_attach is NULL. With loadable protocols the SPACER dummy protocols
have valid function pointers for all methods to functions returning just
EOPNOTSUPP. Thus the early abort check would not detect immediately that
attach is not supported for this protocol. Instead it would correctly
get the EOPNOTSUPP error later on when it calls the protocol specific
attach function.
Add testing against the pru_attach_notsupp() function pointer to the
early abort check as well.

o Better description of IP fastforwarding. It can do the full thing now
including firewalling.
o Reword the description of ICMP redirects.
o Add references to route(4) and pfil(9).
the final set of traces -- someone with more busdma background
will probably want to review and expand this, as well as port to
other platforms. This tracing is sufficient to identify key
busdma events on i386, and in particular to draw attention to
bounce buffering events that may have a substantial performance
impact.
o Instead of locking and unlocking all over the place, use
lock assertions to make certain that the bfe lock is held
where necessary.
o Create locked and unlocked versions of bfe_init and bfe_start. These
functions can be called from outside the module and by functions
within the bfe module. The calls from outside the module don't
hold the bfe lock so the unlocked versions called by these functions
simple obtain the bfe lock and call the locked version.
- Fix a typo (scp) in the locking macros that only worked because in all the
instances in which it was called the softc pointer happened to be named 'sc'.
- Mark the interrupt MPSAFE

without a mountpoint. In this scenario, there's no useful source for
a label on the vnode, since we can't query the mountpoint for the
labeling strategy or default label.
jest, of most excellent fancy: he hath taught me lessons a thousand
times; and now, how abhorred in my imagination it is! my gorge rises
at it. Here were those hacks that I have curs'd I know not how
oft. Where be your kludges now? your workarounds? your layering
violations, that were wont to set the table on a roar?
Move the skeleton of specfs into devfs where it now belongs and
bury the rest.
