    The changelog doesn't explain the semantics of the new syscall.
    There's a comment way-down-there which I guess suffices, if you hunt
    for it.

    And the changelog doesn't explain why this is being added. Presumably
    seccomp_filter wants/needs this feature but whowhatwherewhenwhy? Spell
    it all out, please.

    The new syscall mode will be documented in the prctl manpage. Please
    cc linux-man@vger.kernel.org and work with Michael on getting this
    done?
