Subject: large resize busted in master

just FYI; I don't know when I'll have time to look into it, but
in case anyone else wants to :)

# rm -f /mnt/test2/16tfile
# touch /mnt/test2/16tfile
# truncate --size 16t /mnt/test2/16tfile
# mkfs.ext4 -F -E lazy_itable_init=1 /mnt/test2/16tfile
# resize/resize2fs /mnt/test2/16tfile 4294967290
resize2fs 1.41.14 (22-Dec-2010)
Resizing the filesystem on /mnt/test2/16tfile to 4294967290 (4k) blocks.
Illegal block number passed to ext2fs_unmark_block_bitmap #4294967295 for block bitmap for /mnt/test2/16tfile
resize/resize2fs: Invalid argument while trying to resize /mnt/test2/16tfile
Please run 'e2fsck -fy /mnt/test2/16tfile' to fix the filesystem
after the aborted resize operation.
