Subject: [GIT PULL] seccomp updates for v5.11-rc1
Date: Tue, 15 Dec 2020 12:30:17 -0800	[thread overview]
Message-ID: <202012151225.4881A90257@keescook> (raw)

Hi Linus,

Please pull these seccomp updates for v5.11-rc1. 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.

Thanks!

-Kees
