[alsa-devel] [PATCH 0/4] ALSA: yet more timer cleanup and fixes

[Takashi Iwai]

Hi,

while looking at the old syzkaller reports, I noticed that there are
still some possible races around closing the timer object.  Here is a
patch set to cover it as well as some relevant cleanups / fixes.

I haven't set stable to Cc in them since they are really corner
cases, and they haven't been tested much.  But they should be safe
(and easy) to backport, too, if any.

  ALSA: timer: Unify timer callback process code

  ALSA: timer: Check ack_list emptiness instead of bit flag
  ALSA: timer: Make snd_timer_close() really kill pending actions
