mkfs: completely abstract the dev IO during format
This change allows for f2fs_format to work on a non-standard device (e.g.
sparse-memory backed file).
Removes direct access to config.fd from within f2fs_format.c.
Now, f2fs_format_device() can be made to work against any device by
providing
f2fs_finalize_device()
f2fs_trim_device()
and the lib2fs.c functions
ASCIIToUNICODE
dev_write
f2fs_cal_crc32
f2fs_set_bit
log_base_2
This will allow Android's fastboot to use f2fs against a libsparse.

f2fs-tools: add fsck.f2fs and dump.f2fs
fsck.f2fs checks file system consistency, but does not repair a broken
file system yet.
dump.f2fs shows the information of a specific inode and makes dump file
of SSA and SIT.
f2fs checks file system consistency as follows:
o When data about used area and its metadata are identical,
f2fs is considered consistent. To verify such consistency, we use
three bitmaps: nat_area_bitmap, sit_area_bitmap, and main_area_bitmap.
First, each bit in nat_area_bitmap corresponds to a nid in NAT.
Second, each bit in sit_area_bitmap corresponds to a valid block in a
segment. This bitmap is same to the total valid_map of f2fs_sit_entries
in SIT.
Last, each bit in main_area_bitmap corresponds to a block in main area
except meta area.
After a consistency check of each block, we set or clear the
corresponding bit of each bitmap.
From the root node, we start consistency check. The verified
information varies according to block type.
1. NODE
- Read information of node block from NAT
- Check if block address is allocated using node info.
- Check if the type of f2fs_summary related to nid in SSA is NODE.
- Update the corresponding bit in nat_area_bitmap.
- Update the corresponding bit in sit_area_bitmap.
- Set the corresponding bit in main_area_bitmap to 1.
- Then, read node block. According to its attribute, explore
inode/direct node/indirect node/double indirect node
recursively.
- If it is an inode block, we also check its xattr and hard link.
2. DATA
- Check if the type of f2fs_summary related to nid in SSA is DATA.
- Set the corresponding bits of sit_area_bitmap and
main_area_bitmap to visited
- If it is a dentry block, traverse each dentries that may be
regular
file or directory. At this time, it will check inode block again.
Finally, we verify whether
- every nat_area_bitmap is visited
- any unreachable hard link exists
- values of sit_area_bitmap and main_area_bitmap are identical
- total_valid_block_count/node_count/inode_count are correct
Usage:
o fsck.f2fs
# fsck.f2fs /dev/sdx
options:
-d debug level [default:0]
o dump.f2fs
# dump.f2fs -i [ino] /dev/sdx
# dump.f2fs -s 0~-1 /dev/sdx (SIT dump)
# dump.f2fs -a 0~-1 /dev/sdx (SSA dump)
options:
-d debug level [default:0]
-i inode no (hex)
-s [SIT dump segno from #1~#2 (decimal), for all 0~-1]
-a [SSA dump segno from #1~#2 (decimal), for all 0~-1]

Sync the version management
For debian packaing, I should have matched the previous verions, v1.1.0.
So, this is the start of f2fs-tools version.

Bug fix: Fix overflow when calculating block address
This patch fixes the bug as follows.
"I'm trying to roll out f2fs on top of SDHC card and faced with following
issue - after mounting card I cannot read device root entry. It returns
-1 EINVAL (entry too big).
getdents(3, /* 1 entries */, 32768) = 24
getdents(3, 0x1082c88, 32768) = -1 EINVAL (Invalid argument)"
reported by Ruslan N. Marchenko [me@ruff.mobi].
This bug is easily reproducible and I couldn't have checked the mount
entry cautiously.
Due to the bug, f2fs couldn't get default dentries, . and .., in the root
directory. In the case of other newly created directories, that's fine.
The problem was the overflow during casting variables while calculating the
block address of the root dentry block.
In order to avoid that, I simply split the equation under consideration of
the casting issue.

Bug fix: store superblocks with correct offset
There are two superblock writes in mkfs.f2fs.
offset: 0 1024 4095 5119 8191
|------> 1'st superblock ----|--------> 2'nd superblock ----|
Therefore, each superblocks has 1024 byte-size offset.

Enhancement: shorten umount time
When f2fs is unmounted cleanly, it stores active summmary blocks of nodes in the
checkpoint pack in order to avoid reconstruct all of them at the later mount
time. Previously, mkfs didn't prepare that, which is why the initial mount time
is so huge.

>From Vyacheslav Dubeyko.
I added an uuid facility for the serial number.

Enhancement: add i_atime and i_generation
"You appear to have dropped i_btime - no big deal, you weren't using it anyway.
However if you ever want to support NFS export you will need some value which
is assigned when the inode is allocated and never changed until it is
de-allocated. This is used to detect when an NFS file-handle refers to a
previous incarnation of an inode and so should be rejected as STALE.
i_btime could have possibly provided this, but not any more. You might want
to add something back.
ext3 uses "i_generation" and has an 's_next_generation' in the superblock to
ensure that each new inode gets a new generation number.
You've also dropped i_atime. I can certainly understand the desire to do
that, but I wonder if it is entirely wise. There are some use-cases where
i_mtime is a poor substitute.
Also 'current_depth' looks a little odd without a 'i_' prefix. It wouldn't
hurt to have a comment noting that it is for directories."
