Date: Sat, 28 Nov 2015 22:41:36 +0000

 Module Name:	src
 Committed By:	pgoyette
 Date:		Sat Nov 28 22:41:36 UTC 2015
 
 Modified Files:
 	src/external/cddl/osnet/dev/dtrace: dtrace_modevent.c
 
 Log Message:
 When loading the module, if devsw_attach() fails, call dtrace_unload()
 to undo the effects of dtrace_load().  And if dtrace_unload() fails,
 panic (since we can't get the system back to its earlier stable state).
 
 When unloading the module, call devsw_detach() first, to lock out any
 new access.  Then call dtrace_unload().  If dgtrace_unload() fails,
 reattach the devsw, and if that fails, panic.
 
 Implements fixes described in PR kern/43032
