    Subject[PATCH 03/16] tools headers uapi: Sync prctl.h with the kernel sources
    Date
    From: Arnaldo Carvalho de Melo <acme@redhat.com>

    To get the changes in ba8308856564 ("arm64: add prctl control for
    resetting ptrauth keys"), that introduce a prctl with a name that needs
    to be catch by the prctl cmd table generator, which will be done in the
    next cset.
