JBD takes another, and in some ways better, approach.
JBD使用另外一种(从某种意义来说是更好的)方法。
JBD Track Factory, established in 2000, is a professional manufacturer of (metal halogen) spotlights.
JBD金巴迪导轨厂，始创于2000年，是一家专业生产(金卤)导轨射灯的厂家。
The JBD has been designed for the express purpose of implementing a journal on any kind of block device.
JBD被设计成在任何块设备上实现日志的特殊目的。
Rather than recording spans of bytes that must be changed, JBD stores the complete modified filesystem blocks themselves.
JBD存储完整的被修改的文件系统块本身，而不是记录必定会被更改的字节范围。
By doing so, the JBD is given the appropriate opportunities to manage the journal on behalf of the ext3 filesystem driver.
通过执行这些操作，给予了JBD代表ext3文件系统驱动程序管理日志的适当机会。
The approach that the JBD USES is called physical journaling, which means that the JBD USES complete physical blocks as the underlying currency for implementing the journal.
JBD所使用的方法称为物理日志记录，这意味着JBD使用完整的物理块，作为实现日志的主要媒介。
For example, the ext3 filesystem code will inform the JBD of modifications it is performing, and will also request permission from the JBD before modifying certain data on disk.
例如，ext3文件系统代码将正在执行的修改告知JBD，并且还会在修改磁盘上包含的特定数据之前请求 JBD的许可。
It's quite a nice arrangement, and because the JBD is being developed as a separate, generic entity, it could be used to add journaling capabilities to other filesystems in the future.
这是很好的安排，因为JBD是作为一个单独的、一般实体而开发的，将来它可以用于向其它文件系统添加日志记录能力。
