The split of these patches is a bit odd, either do all in one patch or one patch per filesystem instead of those groups. That beeing said if we go down this way I would prefer if we go down all the way, that is convert the remaining few filesystems that pass a check_acl argument to generic_permission (btrfs, gfs2, ocfs2) and just kill off that argument. After that there is another step we can easily go: as we now cache the ACLs in the generic inode instead of the per-fs one we can move the get_cached_acl call to your acl_permission_check helper (for gfs2/ocfs2 that don't cache ACLs it will always fail), and not call out to the fs for the fast path at all. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
