Messages in this thread Patch in this message | | | Date | Mon, 30 Jan 2006 14:06:11 +0300 | From | Oleg Nesterov <> | Subject | [PATCH 2/3] pidhash: don't use zero pids |
| |
daemonize() calls set_special_pids(1,1), while init and kernel threads spawned from init/main.c:init() run with 0,0 special pids. This patch changes INIT_SIGNALS() so that that they run with ->pgrp == ->session == 1 also.
This patch relies on fact that swapper's pid == 1.
Now we never use pid == 0 in kernel/pid.c.
[ Andrew, this patch obsoletes "[PATCH] pid: Don't hash pid 0.", filename pid-dont-hash-pid-0.patch ].
