It's not the first time I submit them, hope they go in this time, for the happiness of all the anti-seccomp and in turn anti-cpushare folks out there. 1) this reduces the number of bytes that seccomp takes when enabled (in ram terms) 2) this makes seccomp absolutely zerocost at runtime (in cpu terms, even for the scheduler and not only for the syscalls) As soon as the money is allowed in (and no it's not a technical problem anymore, the code is completely finished and tested in the sandbox since two weeks ago), the userland package may become a bit more spread than only in debian, and I hardcoded those prctl in the userland side, so I wouldn't like breakage to spread if somebody registers those prctl numbers in the kernel for something else.
