inode store i_sync_tid and i_datasync_tid in order to optimize journal flushes and wait for commits only when necessary, but fields are declared as tid_t(not atomic_t as it done in ext3) so we have not synchronization between readers and writers, so gcc and cpu is allowed to perform prefetch, cache and other stuff. Looks like a bug, right? -- 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
