resize2fs: don't try to resize below calculated minimum
Without a force flag, don't allow resize2fs to even start resizing

resize2fs: fix minimum size calculations
The extra padding added to the minimum size calculations:
/*
* We need to reserve a few extra blocks if extents are
* enabled, in case we need to grow the extent tree. The more
* we shrink the file system, the more space we need.
*/
if (fs->super->s_feature_incompat & EXT3_FEATURE_INCOMPAT_EXTENTS)
blks_needed += (fs->super->s_blocks_count - blks_needed)/500;
can go quite wrong if we've already added up more "blks_needed"
than our current size, and the above subtraction wraps. This can
easily happen for a filesystem which is almost completely full.
In this case, just return the current fs size as the minimum and
be done with it.
With this fix we could probably call calculate_minimum_resize_size()
for each resize2fs invocation and refuse to resize smaller than that?

resize2fs: fix ENOSPC corruption case
http://people.redhat.com/esandeen/livecd-creator-imagefile.bz2
contains an image (for now) which, when resized to 578639, corrupts
the filesystem.
This is a bit crazy, I guess, because the fs currently has only
1 free block, but still, we should be graceful about the failure.
Perhaps it would make sense to check the requested valuea against
the minimum value resize2fs would compute for "-P" and fail (at
least without a force).
But in any case, this exposed 2 bugs when moving that one block
required an extent split, which is what hit the ENOSPC.
For starters, ext2fs_extent_set_bmap() in the "(re/un)mapping last
block in extent" case was replacing the old extent before the
new one was created; when the new extent creation failed, it
left us in an inconsistent state. Simply changing the order of
the two should fix this problem.
Next, ext2fs_extent_insert was calling ext2fs_extent_delete()
on *any* error, including one caused by failure to allocate a new
block to split the node to hold that extent ... the handle was left
unchanged, and we deleted the -original- extent.
As a quick fix for this, just don't do the delete if we fail the split,
though this may need to be smarter. I don't think we have terribly
consistent behavior about where a handle is left on various errors.

e2fsck: initialize error handling before journal replay
One of our customers hit a temporary IO error during an e2fsck run during

e2fsck automatically discarding the journals and recreating them on several
filesystems on this node without any prompting from the user:
end_request: I/O error, dev sdg, sector 484832
Buffer I/O error on device sdg, logical block 60604

The following patch moves the e2fsck error handler initialization earlier
in the e2fsck startup code before the journal is processed, so that the
user will be prompted for an action. This is the first IO that is not
part of ext2fs_open() where fs->io is first initialized.
It doesn't seem possible to initialize the error handlers for the initial
filesystem open without changing the prototype for ext2fs_open2(). If we
are getting a new ext2fs_open3() prototype for 64-bit it might make sense
to add at least "read_error" as a parameter ("write_error" is not strictly
necessary for the open and could be set afterward).

We can get into a situation in blkid where whole disks remain
in the cache, even though partitions are found. For labels

1) create a sun disklabel w/partitions
2) mkfs the first partition (at sector 0)
3) remove the partition table
4) run blkid - this finds the fs on the whole disk, places in cache
5) recreate the partition table
6) run blkid - this finds the partition, places in cache
And now we have both /dev/sda and /dev/sda1 in cache.
There are heuristics in probe_all to avoid putting the whole disk
in cache if it has partitions, but there is nothing to remove the

If we need to shrink the inode table, we need to make sure the inodes
contained in the part of the inode table we are vacating don't get
reused as part of the filesystem shrink operation. This wasn't a
problem with ext3 filesystems, since the inode table was located in
the block group that was going away, so that location was not eligible
for reallocation.
However with ext4 filesystems with flex_bg enabled, it's possible for
a portion of the inode table in the last flex_bg group to be
deallocated, but in a part of the filesystem which could be used as
data blocks. So we must mark those blocks as reserved to prevent
their reuse, and adjust the minimum filesystem size calculation to

resize2fs: Release bitmap and itable blocks in flex_bg filesystems
Previously resize2fs assumed that bitmap and inode table blocks were
always located in their respective block group. However, this is no
longer true with flex_bg. So it is necessary to check all of the
block groups which will be truncated to see if they have metadata
blocks that need to be marked as no longer being in use in the new,
shrunk filesystem.
This bug fixes resize2fs -M, which would otherwise fail because
without the released blocks, there would not be enough space in the
filesystem. This bug also avoids (mostly harmless) filesystem
corruptions reported by e2fsck regarding blocks marked in use but not
actually used (these being the bitmap and inode table blocks
associated with the truncated block groups).
Note: in theory it is possible to have block group N utilize bitmap
and inode table blocks in block group N+X with flex_bg. At the moment
neither mke2fs nor e2fsck will create filesystems like this, which is
good, because resize2fs doesn't handle this case correctly.
