[PATCH] Call exit_itimers from do_exit, not __exit_signal
When I originally moved exit_itimers into __exit_signal, that was the only place where we could reliably know it was the last thread in the group dying, without races. Since then we've gotten the signal_struct.live counter, and do_exit can reliably do group-wide cleanup work. This patch moves the call to do_exit, where it's made without locks. This avoids the deadlock issues that the old __exit_signal code's comment talks about, and the one that Oleg found recently with process CPU timers. [ This replaces e03d13e985d48ac4885382c9e3b1510c78bd047f, which is why it was just reverted. ] Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
