| 1. | 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。 |
| 2. | Here are a couple of neat things about the jbd - managed ext3 journal
关于jbd管理的ext3日志有一些巧妙的特性。 |
| 3. | Because both data and metadata are journaled , jbd can use the journal to bring both metadata
因为数据和元数据都被记录， jbd可以使用日志将元数据 |
| 4. | 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。 |
| 5. | Which means that the jbd uses complete physical blocks as the underlying currency for implementing the journal
，这意味着jbd使用完整的物理块，作为实现日志的主要媒介。 |
| 6. | In ext3 , the journaling code uses a special api called the journaling block device layer , or jbd
在ext3里，日志记录代码使用一个特殊的称为“日志记录块设备”层或jbd的api 。 |
| 7. | 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。 |
| 8. | 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。 |
| 9. | In this mode called " data journal " mode , the jbd journals all changes to the filesystem , whether they are made to data or metadata
在这种方式下（称之为“ data = journal ”方式） ， jbd将所有对数据和元数据的更改都记录到文件系统中。 |
| 10. | 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。 |
