In a desperate attempt to screw up /proc one more time, I added some
proc fixes, wrote test module which creates and removes simple proc
file, then ran a) modprobe/rmmod loop, b) cat /proc/foo/bar loop,
c) LTP loop. So far so good -- survived overnight run.
While rebooting into new kernel, kernel died:
