#     Merge branch 'signal-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull signal/exit/ptrace updates from Eric Biederman:
#      "This set of changes deletes some dead code, makes a lot of cleanups
#       which hopefully make the code easier to follow, and fixes bugs found
#       along the way.
#     
#       The end-game which I have not yet reached yet is for fatal signals
#       that generate coredumps to be short-circuit deliverable from
#       complete_signal, for force_siginfo_to_task not to require changing
#       userspace configured signal delivery state, and for the ptrace stops
#       to always happen in locations where we can guarantee on all
#       architectures that the all of the registers are saved and available on
#       the stack.
#     
#       Removal of profile_task_ext, profile_munmap, and profile_handoff_task
#       are the big successes for dead code removal this round.
#     
#       A bunch of small bug fixes are included, as most of the issues
#       reported were small enough that they would not affect bisection so I
#       simply added the fixes and did not fold the fixes into the changes
#       they were fixing.
#     
#       There was a bug that broke coredumps piped to systemd-coredump. I
#       dropped the change that caused that bug and replaced it entirely with
#       something much more restrained. Unfortunately that required some
#       rebasing.
#     
#       Some successes after this set of changes: There are few enough calls
#       to do_exit to audit in a reasonable amount of time. The lifetime of
#       struct kthread now matches the lifetime of struct task, and the
#       pointer to struct kthread is no longer stored in set_child_tid. The
#       flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is
#       removed. Issues where task->exit_code was examined with
#       signal->group_exit_code should been examined were fixed.
#     
#       There are several loosely related changes included because I am
#       cleaning up and if I don't include them they will probably get lost.
#     
#       The original postings of these changes can be found at:
#          https://lkml.kernel.org/r/87a6ha4zsd.fsf@email.froward.int.ebiederm.org

#     
#       I trimmed back the last set of changes to only the obviously correct
#       once. Simply because there was less time for review than I had hoped"
