#     Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull SIGCHLD fix from Eric Biederman:
#      "Christof Meerwald reported that do_notify_parent has not been
#       successfully populating si_pid and si_uid for multi-threaded
#       processes.
#     
#       This is the one-liner fix. Strictly speaking a one-liner plus
#       comment"
#     
#     * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
#       signal: Avoid corrupting si_pid and si_uid in do_notify_parent
