Subject: [PATCH] 2/2 daemonize calls reparent_to_init() cleanup
Date: Wed, 04 Sep 2002 13:51:08 +1000	[thread overview]
Message-ID: <20020904035108.8DA012C057@lists.samba.org> (raw)

Name: daemonize() calls reparent_to_init cleanup
Author: Rusty Russell
Status: Cleanup

D: This makes daemonize() call reparent_to_init() itself, as long
D: suggested for 2.5, and fixes the callers so they don't call it again.
D: Also fixes callers which set current->tty to NULL themselves (also
D: no longer neccessary).
