Merge tag 'seccomp-v5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
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)"
