Hi.

I will try to change the journaling interface of ext3 from jbd into jbd2.

jbd2 has new features from jbd. For example, it includes the integrity 
improvement features. The body of ext3 is already enough quality. If ext3 
changes the journaling interface from jbd into jbd2, ext3 filesystem with jbd2
interface may get better integrity than with the jbd interface.
(jbd2 is aggressively being developed now, so I think we are glad if we can 
get the effect of the development of jbd2 for ext3.)

And ext3 is as de facto standard filesystem, so jbd2 component will be used 
by more people than now if ext3 has the jbd2 interface. If many people used 
the jbd2 interface of ext3, the jbd2 component would get more chances to 
improve the quality and performance and so on. 

Besides, ext3 is now the only user of jbd. 
(ocfs2 which was the user of jbd is now the user of jbd2.)

Do you want the jbd2 interface of ext3?
If you want the jbd2 interface, I will try to implement one.
