The filename of the patch is: alsa-pcm-return-0-when-size-start_threshold-in-captu.patch and it can be found in the queue-4.19 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.
Hi Sasha.
This patch was reverted by the commit 932a81519572156a88db ("ALSA: pcm: Comment why read blocks when PCM is not running"):
This avoids bringing back the problem introduced by 62ba568f7aef ("ALSA: pcm: Return 0 when size < start_threshold in capture") and fixed in 00a399cad1a0 ("ALSA: pcm: Revert capture stream behavior change in blocking mode"), which prevented the user from starting capture from another thread.
Should this be queued anyway? If yes, I think it should also be queued the fix and the commit above.
