Good point; this is going to make supporting a read-only mount that doesn't replay the journal very difficult to implement for data=journal mode, since it would mean intercepting the actual block I/O read functions for data reads, which is outside of fs/ext4 in the generic fs/ and mm/ functions. Doing it for metadata blocks will be annoying, but at least it's all inside fs/ext4. - Ted -- 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
