In downstream Raspberry Pi kernel we noticed that audio didn't work as expected, we got stuttering and overruns/underruns. Here's the link to the original discussion on GitHub: https://github.com/raspberrypi/linux/issues/1517 This issue is caused by a small bug in the period-splitting-code and fixed by the first patch. The second patch, avoiding very small chunks, is mainly a precaution. While small chunks are not known to have caused any problems so far they have the potentical to cause very hard to track down issues. So better avoid such situations in the first place.
