worker_thread: don't play with SIGCHLD and numa policy
worker_thread() inherits ignored SIGCHLD and numa_default_policy() from its parent, kthreadd. No need to setup this again. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Acked-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
