#     Merge tag 'seccomp-v5.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
#     
#     Pull seccomp fixes from Kees Cook:
#      "This fixes a rare race condition in seccomp when using TSYNC and
#       USER_NOTIF together where a memory allocation would not get freed
#       (found by syzkaller, fixed by Tycho).
#     
#       Additionally updates Tycho's MAINTAINERS and .mailmap entries for his
#       new address"
#     
#     * tag 'seccomp-v5.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
#       seccomp: don't leave dangling ->notif if file allocation fails
#       mailmap, MAINTAINERS: move to tycho.pizza
#       seccomp: don't leak memory when filter install races
