ext3: fix online resize bug
There is a bug when we are trying to verify that the reserve inode's double indirect blocks point back to the primary gdt blocks. The fix is obvious, we need to mod the gdb count by the addr's per block. You can verify this with the following test case dd if=/dev/zero of=disk1 seek=1024 count=1 bs=100M losetup /dev/loop1 disk1 pvcreate /dev/loop1 vgcreate loopvg1 /dev/loop1 lvcreate -l 100%VG loopvg1 -n looplv1 mkfs.ext3 -J size=64 -b 1024 /dev/loopvg1/looplv1 mount /dev/loopvg1/looplv1 /mnt/loop dd if=/dev/zero of=disk2 seek=1024 count=1 bs=50M losetup /dev/loop2 disk2 pvcreate /dev/loop2 vgextend loopvg1 /dev/loop2 lvextend -l 100%VG /dev/loopvg1/looplv1 resize2fs /dev/loopvg1/looplv1 without this patch the resize2fs fails, with it the resize2fs succeeds.
