#     Merge tag 'ptrace-cleanups-for-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull ptrace cleanups from Eric Biederman:
#      "This set of changes removes tracehook.h, moves modification of all of
#       the ptrace fields inside of siglock to remove races, adds a missing
#       permission check to ptrace.c
#     
#       The removal of tracehook.h is quite significant as it has been a major
#       source of confusion in recent years. Much of that confusion was around
#       task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled making the
#       semantics clearer).
#     
#       For people who don't know tracehook.h is a vestiage of an attempt to
#       implement uprobes like functionality that was never fully merged, and
#       was later superseeded by uprobes when uprobes was merged. For many
#       years now we have been removing what tracehook functionaly a little
#       bit at a time. To the point where anything left in tracehook.h was
#       some weird strange thing that was difficult to understand"
