Oleg Nesterov 547679087b [PATCH] send_sigqueue: simplify and fix the race ... send_sigqueue() checks PF_EXITING, then locks p->sighand->siglock. This is unsafe: 'p' can exit in between and set ->sighand = NULL. The race is theoretical, the window is tiny and irqs are disabled by the caller, so I don't think we need the fix for -stable tree. Convert send_sigqueue() to use lock_task_sighand() helper. Also, delete 'p->flags & PF_EXITING' re-check, it is unneeded and the comment is wrong.
