[Patch 1]ext3_fsblk_t, ext3_grpblk_t and type fixes.
defines ext3_fsblk_t and ext3_grpblk_t, and the printk format string
for filesystem wide blocks.
This patch classifies all block group relative blocks, and
ext3_fsblk_t blocks occurs in the same function where used to
be confusing before. Also include kernel bug fixes for filesystem
wide in-kernel block variables. There are some fileystem wide
blocks are treated as int/unsigned int type in the kernel currently,
especially in ext3 block allocation and reservation code.
This patch fixed those bugs by converting those variables to
ext3_fsblk_t(unsigned long) type.
