Subject: [PATCH 0/3] make task_struct->signal stable
Date: Fri, 19 Mar 2010 19:40:13 +0100	[thread overview]
Message-ID: <20100319184013.GA504@redhat.com> (raw)

Depends on

	[PATCH 1/4] exit: exit_notify() can trust signal->notify_count < 0
	[PATCH 2/4] exit: change zap_other_threads() to count sub-threads
	[PATCH 3/4] exit: avoid sig->count in de_thread/__exit_signal synchronization
	[PATCH 4/4] exit: avoid sig->count in __exit_signal() to detect the group-dead case

	[PATCH 1/2] posix-cpu-timers: avoid "task->signal != NULL" checks
	[PATCH 2/2] ia64: ptrace_attach_sync_user_rbs: avoid "task->signal != NULL" checks

	[PATCH] move tty_kref_put() outside of __cleanup_signal()

See the changelog in 1/3. IIRC, this was suggested by Ingo a long ago.

Note! This series is not complete, it needs some conclusive cleanups and
a lot more cleanups are possible because task->signal is never NULL. 3/3
is the "random" example.

Oleg.
