[PATCH v3 00/11] General cleanups and fixes from SECCOMP patchset

[benjamin at sipsolutions.net]

From: Benjamin Berg <benjamin at sipsolutions.net>

Hi,

the SECCOMP patchset is not ready yet as I need to change it quite a bit
for the FD passing based security model that was proposed.

Until then, the cleanups and small fixes from the start of the patchset
are still relevant and it could be nice to pull them in anyway. So I am
resending just these.

I purely rebased the patchset. There should be no other differences
between v2 and v3 here.

Benjamin
