If group\nmembership changes during the wait and the sleep ends by signal or\ntimeout (so autoremove_wake_function() does not run), finish_wait() is\nskipped and snd_pcm_drain() returns with the entry still queued on that\nstream's sleep list; a later wake_up() then walks a freed stack frame.\nThis is reachable by unlinking either the drained or the draining stream.\n\nUnlike the close path (snd_pcm_drop() -> snd_pcm_post_stop()),\nsnd_pcm_unlink() never wakes the sleep queues.  Wake every group member\nunder the group lock before the membership change, so a linked drainer is\nreleased and drops its entry while the streams are still grouped.\n\nThe window was opened when snd_pcm_link_rwsem stopped being held across\nthe wait and the removal became conditional on group membership (see\nFixes). The later switch to finish_wait() kept that conditional removal,\nso the signal/timeout case remained."
