[PATCH] 2.5 ext3 ino_t removal

[Andreas Dilger]

This patch against 2.5.53 removes my erronous use of ino_t in a
couple of places in the ext3 code.  This has been replaced with unsigned
long (the same as is used for inode->i_ino).  This patch matches the fix
submitted to 2.4 for fixing 64-bit compiler warnings, and also replaces a
couple of %ld with %lu to forestall output wierdness with filesystems with
a few billion inodes.

Cheers, Andreas
