We don't need to issue a barrier after a call to sync_inode() or ext[34]_force_commit(), since those functions will issue a barrier for us. It would probably be a good idea to use blktrace to test and make sure that we have one and exactly one barrier op issued for each fsync(). - 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
