Those paths are above the level where shm_get_policy() is called. It may be that shm_get_policy() doesn't need to recapitulate them if it's only ever called through such codepaths. It's not clear to me whether that's intended as an invariant or is coincidental and not guaranteed for future callsites. -- wli - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
