sys/sys taskqueue.h
sys/kern subr_taskqueue.c
Log:
Implement taskqueue_block() and taskqueue_unblock(). These functions allow
the owner of a queue to block and unblock execution of the tasks in the
queue while allowing tasks to continue to be added queue. Combining this
with taskqueue_drain() allows a queue to be safely disabled. The unblock
function may run (or schedule to run) the queue when it is called, just as
calling taskqueue_enqueue() would.
