#     Merge tag 'seccomp-v5.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
#     
#     Pull seccomp fixes from Kees Cook:
#      "Syzbot found a use-after-free bug in seccomp due to flags that should
#       not be allowed to be used together.
#     
#       Tycho fixed this, I updated the self-tests, and the syzkaller PoC has
#       been running for several days without triggering KASan (before this
#       fix, it would reproduce). These patches have also been in -next for
#       almost a week, just to be sure.
#     
#        - Add logic for making some seccomp flags exclusive (Tycho)
#     
#        - Update selftests for exclusivity testing (Kees)"
