#     
#     Pull seccomp updates from Kees Cook:
#      "The major change here is finally gaining seccomp constant-action
#       bitmaps, which internally reduces the seccomp overhead for many
#       real-world syscall filters to O(1), as discussed at Plumbers this
#       year.
#     
#        - Improve seccomp performance via constant-action bitmaps (YiFei Zhu
#          & Kees Cook)
#     
#        - Fix bogus __user annotations (Jann Horn)
#     
#        - Add missed CONFIG for improved selftest coverage (Mickaël Salaün)"
