Package: linux Version: 4.9.30 The LTP testcase fanotify07 creates hanging processes with debian kernel 4.9.30 on the hppa platform.
In the source code of LTP's fanotify07.c testcase one can read: * Kernel crashes should be fixed by: * 96d41019e3ac "fanotify: fix list corruption in fanotify_get_response()" * * Kernel hangs should be fixed by: * 05f0e38724e8 "fanotify: Release SRCU lock when waiting for userspace response" It seems upstream commit 05f0e38724e8 "fanotify: Release SRCU lock when waiting for userspace response" is missing in stable kernel 4.9.30 (and debian kernel), which explains why the testcase hangs. I didn't checked if the kernel crash fix is in 4.9.30. Can you backport at least the commit 05f0e38724e8 ? Thanks, Helge
