#     Merge branch 'exec-update-lock-for-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull exec-update-lock update from Eric Biederman:
#      "The key point of this is to transform exec_update_mutex into a
#       rw_semaphore so readers can be separated from writers.
#     
#       This makes it easier to understand what the holders of the lock are
#       doing, and makes it harder to contend or deadlock on the lock.
#     
#       The real deadlock fix wound up in perf_event_open"
