[alsa-devel] pcm_lib.c: XRUN alsa-back-porting

[Timur Tabi]

A customer is reporting that he's seeing this message every now and then, but
when I try to examine the kernel source code, I don't see the source of it.  In
fact, when I do a google search of "alsa-back-porting", I get zero hits.  So
maybe the customer is using some older kernel, but when I scan the git change
history for sound/core/pcm_lib.c, I still don't see it.

So can someone tell me what "alsa-back-porting" means, and where it comes from?
