It's not possible to supply the tree_root via mount option, but it should be possible to modify the superblock to point the tree_root to the one you've found, in a similar way that the -o recovery does that, but this hasn't been done before and "minor" details may make it complicated (like getting the transaction number in sync, as the tree_root has latest-1). david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
