Why would we need to skip the filemap_write_and_wait_range call here? If we're doing direct I/O we should not have any pages in this regions anyway. You're also not skipping it in the generic implementation as far as I can see, so I see no point in doing it just in XFS. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
