#     Merge branch 'ucount-fixes-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull ucount cleanups from Eric Biederman:
#      "While working on the ucount fixes a for v5.15 a number of cleanups
#       suggested themselves.
#     
#       Little things like not testing for NULL when a pointer can not be NULL
#       and wrapping atomic_add_negative with a more descriptive name, so that
#       people reading the code can more quickly understand what is going on"
#     
#     * 'ucount-fixes-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
#       ucounts: Use atomic_long_sub_return for clarity
#       ucounts: Add get_ucounts_or_wrap for clarity
#       ucounts: Remove unnecessary test for NULL ucount in get_ucounts
#       ucounts: In set_cred_ucounts assume new->ucounts is non-NULL
