It _would_ deadlock, I mean. They each have their own strategy to avoid it, for now. jffs2 and btrfs just don't provide export_ops so they avoid the problem, but we'd _like_ to be able to export them. xfs has the hack I've just transplanted. gfs2 has a 'lock is owned by me' check. Not sure about the others. -- David Woodhouse Open Source Technology Centre David.Woodhouse@xxxxxxxxx Intel Corporation -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
