Then can you also take [PATCH -mm v2] do_notify_parent: sanitize the valid_signal() checks https://lore.kernel.org/all/abld-ilvMEZ7VgMw@redhat.com/ which I sent a minute ago on top of this patch? (I have trimmed the huge CC, so you wasn't CC'ed). Cough... and may be another/unrelated [PATCH] pidfd_prepare: don't pass O_RDWR to pidfs_alloc_file() https://lore.kernel.org/all/aZ8gwQYpIjVktcOs@redhat.com/ which I sent you almost a month ago? Oleg.
