Mark Johnston 1e91412e40 Don't set the mirror GEOM softc to NULL in g_mirror_destroy(). ... At this point we have not rendezvous'ed with the mirror worker thread, and I/O may still be in flight. Various I/O completion paths expect to be able to obtain a reference to the mirror softc from the GEOM, so setting it to NULL may result in various NULL pointer dereferences if the mirror is stopped with -f or the kernel is shut down while a mirror is synchronizing. The worker thread will clear the softc pointer before exiting. Tested by: pho MFC after: 2 weeks Sponsored by: Dell EMC Isilon		2017-04-14 17:08:37 +00:00
