Jes had a pretty badly corrupted image which made the minimum size

We'll eventually bail out for an unmounted filesystem if it's marked

quota: fix e2fsck so we update the quota file correctly
In scan_dquota_callback() we were copying dqb_off from the on-disk
dquot structure to the dqot structure that we have constructed in
memory. This is a bad idea, because if we detect that the quota inode
is corrupted and needs to be replaced, when we later write out the
inode, the fact that we have a non-zero dqb_off value means that quota
routines will not bother updating the quota tree index, since
presumably the quota tree index already has an entry for this dqot.
The problem is that e2fsck, the only user of these functions, has
zapped the quota inode so it can be written from scratch. So this
means the index for the quota records are not written out, so the
kernel can not find any of the records in the quota inodes. Oops.
The fix is simple; there is no reason to copy the dqb_off field into
the quota_dict copy of struct dquot.

resize2fs: refine minimum required blocks for flex_bg file systems
The previous commit exposed bugs in the calculation for flex_bg file
systems. The problem is that since (by default) we keep the metadata
blocks for the flex_bg in the first block group of the flex_bg, and
because we don't want to overwrite metadata blocks used by the
original file system with data blocks make life easier in case the
resize is aborted for some reason, we need to treat all of the
metadata blocks in the existing flex_bg has in use for the purposes of
calculate_minimum_resize_size().
Even though this means we need to reserve more data blocks to avoid
running out of space, the net result of these two commits is a net
savings in how much we can shrink a file system.
Using the following test sequence:
mke2fs -F -t ext4 /tmp/foo.img 2T
resize2fs -M /tmp/foo.img
resize2fs -M /tmp/foo.img
resize2fs -M /tmp/foo.img
Here is the comparison in the resulting file systems between the old
and new resize2fs (units are in 4k blocks):
resize #1 resize #2 resize #3
old resize2fs 1117186 45679 43536
new resize2fs 48784 37413 37392

e2fsprogs: Disallow tune2fs enabling sparse_super with ext4 meta_bg enabled
When meta_bg feature is enabled, group descriptor block is allocated
every 128 block group (or every 64 block group if 64bit feature is
enabled).
In such situation, files in block group more than #128 will be removed
if sparse_super feature is enabled with tune2fs and afterwards
necessary e2fsck running.
Because tune2fs does not reallocate group descriptor blocks but just
set sparse_super feature. If ext4 has sparse_super,
ext2fs_descriptor_block_loc2() called by e2fsck thinks the block group
(e.g. #128) that it has group descriptor block at the head offset. But
that offset is used as backup super block before. So e2fsck fixes
ext4 based on invalid group descriptor blocks and this cause data
lost.
The patch avoids this problem simply by disallow tune2fs enabling
sparse_super if meta_bg is enabled.
Steps to reproduce:
1. Create ext4 which has meta_bg, ^sparse_super and 129+ block groups.
# mke2fs -t ext4 -O meta_bg,^resize_inode,^sparse_super DEV 17G
# mount DEV /MP
2. Create direcotry and files which use block group #128's metadata.
# echo $((8192*128+1)) > /sys/fs/ext4/DEV/inode_goal
# mkdir /MP/DIR
# for i in $(seq 1 100); do dd if=/dev/urandom of=/MP/DIR/file$i bs=1024 count=10; done
3. Enable sparse_super with tune2fs then execute e2fsck.
Data in block group #128 will be lost!!

# tune2fs -O sparse_super DEV
