I shouldn't compose emails so late. :). Oh, but Zach Brown reminds me that if we stat the entries in getdents/hash order, it's roughly random w.r.t. disk location. Newer utils will sort into inode order, I think(?) Might be interesting to strace the ls -l and see if it's doing it in inode order, or not. -Eric -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
