f2fs currently only work with zoned storage devices with a zone
size which is a power of 2 (PO2). So check if a non-power of 2
zoned device is found, and if so disallow its use. This prevents
users from incorrectly using these devices.
This is a non-issue today given today's kernel does not allow NPO2
zoned devices to exist as a block device. But NPO2 zoned devices do exist
so proactively put a stop-gap measure in place to prevent it from being
incorrectly used.

CVE: NA
Signed-off-by: DongSenhao <dongsenhao2@huawei.com>
---------------------------------------
If the following process returns an error,
the quota inode, not the quota file, is damaged.
(fsck_chk_quota_node-->fsck_chk_node_blk-->sanity_check_nid)
The fsck does not have a process to rebuild the quota inode.
Because sanity_check_nid is not passed, fsck->nat_area_bitmap
can not be cleared, and then the NAT of quota will be nullify
during fix_nat_entries.
During the next fsck check, the quota inode check fails
because the address of the quota inode changes to 0.
In addition, in fsck_chk_quota_files-->f2fs_filesize_update,
data is written to address 0.
Therefore, when the quota inode is corrupted, we need to rebuild it.

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

* use c.cache_config.max_hash_collision to set maximum hash

Cache properties:
* Per block save based (block size = f2fs block size = 4K Bytes)
* Device block indices are used to hash (simple modular hash
function) to cache indices.
* A hash collision (when a block is hashed to an already occupied
cache block) will trigger offset-based relocation to max 16
other places, at first empty slot found policy.
* A hash collision with all 17 possible relocating places occupied
will evict the oldest used one (replaced by the new read block).

* On write cache hit, it will update the corresponding cached

* On write cache miss, the data won't be cached.
* Write-through policy only: never delayed write.
* On read cache hit, it returns the cached block.
* On read cache miss, it issues an I/O read to the kernel, and
then caches and returns the block.
* Currently read ahead is not implemented. Yet, the read ahead
