[PATCH] ext3 should use uint for internal inode containers

[Eric Sandeen <sandeen@sandeen.net>]

Talking to sct, he'd prefer to see ext3 continue to use only uints for 
inode number containers which are internal to the filesystem, since the 
filesystem itself can only do 32-bit inode numbers (on-disk format 
restriction), and uint is always 32, while ulong is sometimes 64.  
So, this patch bumps the unsigned longs from 
ext3-inode-numbers-are-unsigned-long.patch back down to unsigned ints.

(this patch applies over that one)

Thanks,

-Eric
