In the case of XFS, logical journaling is a good fit; on high-end hardware, the journal is often the most contentious resource of the entire filesystem.

就XFS而言，逻辑日志记录是很适合的；在高端硬件上，日志经常是整个文件系统中争用最多的资源。

But because ext3 USES complete blocks internally and in the journal, ext3 doesn't deal with as much complexity as it would if it were to implement logical journaling.

但是，因为ext3在文件系统内部和日志中使用完整块，ext3处理的复杂度比实现逻辑日志记录的要小。

Like ReiserFS, XFS USES a logical journal; that is, it does not journal literal filesystem blocks like ext3, and instead USES an efficient on-disk format to log metadata changes.

象reiserfs一样，XFS使用逻辑日志；即，它不象ext3那样将文字文件系统块记录到日志，而是使用一种高效的磁盘格式来记录元数据的变动。

Socially-conscious, anti-establishment rappers like Lupe Fiasco, who wrote a poem in an issue of the Occupied Wall Street Journal last year, are logical proponents.
