As far as the VFS is concerned this should be fairly easily doable, we'd just have to switch O_TMPFILE to the same lookup parent first algorithm used for O_CREAT. The filesystems shouldn't really care at all as the name will never be stored on disk. In fact such a full-path O_TMPFILE would be much nicer than the current one as it has more similar arguments to the normal O_CREAT open that I would document it as the default one, even if the old semantics would have to still be supported for backwards compatibility. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
