Why is inode number 0 even if its journal or meta data ? Also I am
getting *lots* of write per second on a bare metal centos with nothing
running. Its strange. Didn't see it on 3.x.

I am not facing any deadlocks on 2.6.18 but was facing it on 3.x.
freeze_bdev() and thaw_bdev() work correctly on 2.6.18. I will try it
again on 3.x and confirm.

Regards.
