>From the comment in the test case: * 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"
In this case, it's kernel hung, so 05f0e38724e8 should do the trick. However, from a discussion thread [1] for debian it looks like this is difficult to backport.
