hohum, yes. I'll fix that, which will also require a change to xfs_io to be able to set a null string. Will send a V3 in a bit. -Eric -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
