Subject: kjournald - what does this process actually do?

Hi there

I was wondering, what does kjournald actually do. I know it relates to using
jounralised file systems such as ext3 and reiserfs, but that's about it. I
wasn't really hoping to dig through source code, but :P ...

Also, what would cause a kjournald process to go down?

Sorry, it relates to ext3 only, not reiserfs. My bad.
