[PATCH] do_SAK: Don't recursively take the tasklist_lock
By calling send_sig do_SAK is recursively taking the tasklist_lock, which is silly. In addition I just audited the kernel and this was the only place where tasklist_lock is taken inside of task_lock. So this one line change is a general worthwhile cleanup and it increases our options on how to fix the ptrace_attach races. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
