Hi all,

Here's a v6 of the seccomp trap to userspace series. v5 [1] was fairly
quiet, with Christian reminding me that I had forgotten to update the
docs for the ioctl change. Other than that, there are no changes.

Thoughts welcome,

Tycho

seccomp: add a return code to trap to userspace
seccomp: make get_nth_filter available outside of CHECKPOINT_RESTORE
seccomp: add a way to get a listener fd from ptrace
seccomp: add support for passing fds via USER_NOTIF
samples: add an example of seccomp user trap
