Author: jpaetzel Date: Fri Jan 1 17:06:16 2016 New Revision: 293043 URL: https://svnweb.freebsd.org/changeset/base/293043 Log: Unset the gss kernel state when gssd exits When gssd exits it leaves the kernel state set by gssd_syscall(). nfsd sees this and waits endlessly in an unkillable state for gssd to come back. If you had acidentally started gssd then stopped it, then started nfsd you'd be in a bad way until you either restarted gssd or rebooted the system. This change fixes that by setting the kernel state to "" when gssd exits.
