As Al notes, we missed a TIF_NOTIFY_RESUME check which caused any handlers without TIF_SIGPENDING also set to skip the notification: Looks like while it is in the relevant masks *and* checked in do_notify_resume() both on 32bit and 64bit variants since commit ab99c733 ("sh: Make syscall tracer use tracehook notifiers, add TIF_NOTIFY_RESUME.") they are actually *not* reached without simulataneous SIGPENDING, since the actual glue in the callers had not been updated back then and still checks for _TIF_SIGPENDING alone when deciding whether to hit do_notify_resume() or not.
