exit_notify: kill the wrong capable(CAP_KILL) check (CVE-2009-1337)
CVE-2009-1337
commit 432870dab85a2f69dc417022646cb9a70acf7f94 upstream.
The CAP_KILL check in exit_notify() looks just wrong, kill it.
Whatever logic we have to reset ->exit_signal, the malicious user
can bypass it if it execs the setuid application before exiting.
