#     Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull proc fix from Eric Biederman:
#      "While running syzbot happened to spot one more oversight in my rework
#       of proc_flush_task.
#     
#       The fields proc_self and proc_thread_self were not being reinitialized
#       when proc was unmounted, which could cause problems if the mount of
#       proc fails"
#     
#     * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
#       proc: Handle umounts cleanly
