Subject: [PATCH v2 0/3] seccomp: add PR_SECCOMP_EXT and SECCOMP_EXT_ACT_TSYNC

This adds the ability for threads to request seccomp filter 
synchronization across their thread group. To support this, 
seccomp locking on writes is introduced, along with refactoring
of no_new_privs. Races with thread creation are handled via the
tasklist_list. 

I think all the concerns raised during the discussion[1] of the first
version of this patch have been addressed. However, the races involved
have tricked me before. :)

Thanks!
