Justin T. Gibbs 5b326a32ce Prevent live-lock and access of destroyed data in taskqueue_drain_all(). ... Phabric: https://reviews.freebsd.org/D1247 Reviewed by: jhb, avg Sponsored by: Spectra Logic Corporation sys/kern_subr_taskqueue.c: Modify taskqueue_drain_all() processing to use a temporary "barrier task", rather than rely on a user task that may be destroyed during taskqueue_drain_all()'s execution. The barrier task is queued behind all previously queued tasks and then has its priority elevated so that future tasks cannot pass it in the queue. Use a similar barrier scheme to drain threads processing current tasks. This requires taskqueue_run_locked() to insert and remove the taskqueue_busy object for the running thread for every task processed. share/man/man9/taskqueue.9: Remove warning about live-lock issues with taskqueue_drain_all() and indicate that it does not wait for tasks queued after it begins processing.		2015-01-04 19:55:44 +00:00
