https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194727 --- Comment #71 from Hans Petter Selasky <hselasky@FreeBSD.org> --- > If kernel would kill such file descriptors ... Only applications can fully kill file descriptors! It is not possible for the kernel to kill file descriptors in a non-blocking fashion. > I do not care pulse or any other apps, my issue that USB stack is unusable after usb sound adapter disconnected without all apps closes fd. This is the expected behaviour. Remember that the OSS support in pulseaudio was written when detachable audio devices didn't yet exist. So how can you expect it to work accordingly? I'm saying again, the problem is not the kernel, but in user-space. The kernel cannot kill file descriptors like you think, no matter what. It's always the applications responsibility to clean up that as long as it is running, but the kernel can probably kill misbehaving applications after a while. --HPS -- You are receiving this mail because: You are on the CC list for the bug.
