Author: kevans Date: Fri Nov 29 14:46:13 2019 New Revision: 355212 URL: https://svnweb.freebsd.org/changeset/base/355212 Log: tty_rel_gone: add locking assertion We already assert the lock is held later during tty_rel_free(), but it is arguably good form to clarify locking expectations here as well at the top-level that other drivers use.
