Subject: selinux_bprm_committed_creds: use __wake_up_parent()
From: Oleg Nesterov <oleg@xxxxxxxxxx>
(depends on ptrace-__ptrace_detach-do-__wake_up_parent-if-we-reap-the-tracee.patch
which exports __wake_up_parent)
Spotted by Valdis.Kletnieks@xxxxxxx
selinux_bprm_committed_creds() should not play with ->wait_chldexit, now
that __wake_up_parent() is exported change the code to use this helper.
