ext3 中的日志 - 文档
我一直在寻找有关如何在 ext3 中实现日志记录的文档，但找不到任何好的资源。我熟悉 ext2 的内部结构，并且在 Linux 和 Minix 中经历过同样的实现。
您能否向我指出可以帮助我理解 ext3 中日志记录的实现的资源/代码片段？
I have been looking around for documentation on how journalling is implemented in ext3 and couldn't find any good resources. I am familiar with the internals of ext2 and have gone through the implementation of the same in Linux and Minix.
Could you point me towards resources/code snippets which could help me in understanding the implementation of journalling in ext3?

这并不完全是 Ext3 中日志记录的实际工作方式，但我发现有趣的初步工作：http://original.jamesthornton.com/hotlist/linux-filesystems/ext3-journal-design.pdf
这是上述论文作者关于 Ext3 的第一个演示之一： http://olstrans.sourceforge.net/release/OLS2000-ext3/ OLS2000-ext3.html
这一年来已经有了很多改进，但这两个链接将使您深入了解设计日志文件系统时的利害关系。
This is not exactly how the journaling in Ext3 works actually, but a preliminary work I find interesting : http://original.jamesthornton.com/hotlist/linux-filesystems/ext3-journal-design.pdf
And this is one of the first presentation about Ext3 done by the author of the aforementioned paper : http://olstrans.sourceforge.net/release/OLS2000-ext3/OLS2000-ext3.html
There's been a lot of improvement over the year, but these two links will give you a good insight of what is at stake when designing an journaled filesystem.
