NVM Express Zoned Namespace (ZNS) devices can have zone-capacity(zc) less
than the zone-size. ZNS defines a per zone capacity which can be equal
or less than the zone-size. Zone-capacity is the number of usable blocks
in the zone. If zone-capacity is less than zone-size, then the segments
which start at/after zone-capacity are considered unusable. Only those
segments which start before the zone-capacity are considered as usable
and added to the free_segment_count and free_segment_bitmap of the kernel.
In such cases, the filesystem should not write/read beyond the
zone-capacity.
Update the super block with the usable number of blocks and free segment
count in the ZNS device zones, if zone-capacity is less than zone-size.
Set reserved segment count and overprovision ratio based on the usable
segments in the zone.
Allow fsck to find the free_segment_count based on the zone-capacity and

f2fs-tools fails to cross build from source, because its upstream
build system wrongly uses AC_CHECK_FILE. The purpose of the macro is
checking for files on the host system. However here it is used to
check whether a .git directory exists, which is a property of the
build place. A simple "test -d" should be used here. After doing so,
f2fs-tools cross builds successfully.

This patch gives the version info for two libraries.
mkfs/libf2fs_format.la
lib/libf2fs.la
The versioning rule should be:
1. Start with version information of '0:0:0' for each libtool library.
2. Update the version information only immediately before a public release of
your software. More frequent updates are unnecessary, and only guarantee
that the current interface number gets larger faster.
2. If the library source code has changed at all since the last update, then
increment revision (c:r:a) becomes (c:r+1:a).
3. If any interfaces have been added, removed, or changed since the last update,
increment current, and set revision to 0.
4. If any interfaces have been added since the last public release, then
increment age.
5. If any interfaces have been removed or changed since the last public release,
then set age to 0.

The current build system fails to `make distcheck` correctly
for two reasons: 1) Some header files are not listed in the
source files for fsck.f2fs and mkfs.f2fs, and so don't make it

configure.ac, the mock install doesn't add the correct prefix

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
