I went to LKML for context, so I return with context.
When 3.8-rc1 was released, “Rafael J. Wysocki” reported 100% CPU usage by knotify4(part of KDE) on OpenSUSE Thubleweed with pulseaudio as audio server.
At which Mauro Carvalho Chehab replies starting with blaming pulseaudio(why? Srsly, why? I don’t like it, but this is just troll behaviour) and saying pulseaudio(which is NOT knotify4) should not try to use V4L2.
So Linus should have sided with someone who in regression report of KDE using 100% CPU starts blaming pulseaudio and opensuse and double down on blaming pulseaudio? Instead of fixing syscall returning completely unrelated error code. It’s like if your router crashed with message “there is no milk in your fridge”.
Yes. I did not include patch from first person in screenshot because I thought it would make it too boring to read. But it kinda adds even more to context.
Replying to “I get this regression with KDE on this system caused by this commit and here how I fixed it” with “lol, pulseaudio sucks, opensuse sucks” of course will make Linus angry and he will reply not only “no u”, but also “and here’s why”.
I like that Linus is so strict on not breaking user space because this obviously aids with compatibility and it’s probably a big part of why rolling releases work.
I think kernel still has compatibility with paleolithic glibc enabled by default
