[alsa-devel] [PATCH - JACK IO plug v2 0/3] snd_pcm_drain support

[twischer at de.adit-jv.com]

Now in a clean manner as composed patches.


pcm: ioplug: Provide avail helper function
---------
No changes


jack: Avoid call to snd_pcm_avail_update() from JACK thread
---------
v2 uses snd_pcm_uframes_t as type for avail and does not check for avail < 0
becasue snd_pcm_ioplug_avail() will never retrun a value < 0


jack: Update poll_fd also in draining state
---------
