This patch updates sload.f2fs for android build.
- do fsck() after sload() to update quota information.
- return success, if there's no source directory
-C fs_config
-f source directory [path of the source directory]
-p product out directory

This patch adds an option 'extra_attr' in mkfs for enabling v2 f2fs
inode format in kernel codes.
Also this patch makes fsck to support recognize v2 inode format,
below is v2 format description:
Original one:
struct f2fs_inode {
...
struct f2fs_extent i_ext;
__le32 i_addr[DEF_ADDRS_PER_INODE];
__le32 i_nid[DEF_NIDS_PER_INODE];
}
Extended one:
struct f2fs_inode {
...
struct f2fs_extent i_ext;
union {
struct {
__le16 i_extra_isize;
__le16 i_padding;
__le32 i_extra_end[0];
};
__le32 i_addr[DEF_ADDRS_PER_INODE];
};
__le32 i_nid[DEF_NIDS_PER_INODE];
}
Once F2FS_EXTRA_ATTR is set, we will steal four bytes in the head of
i_addr field for storing i_extra_isize and i_padding. with i_extra_isize,
we can calculate actual size of reserved space in i_addr, available
attribute fields included in total extra attribute fields for current
inode can be described as below:
+--------------------+
| .i_mode |
| ... |
| .i_ext |
+--------------------+
| .i_extra_isize |-----+
| .i_padding | |
| .i_prjid | |
| .i_atime_extra | |
| .i_ctime_extra | |
| .i_mtime_extra |<----+
| .i_inode_cs |<----- store blkaddr/inline from here
| .i_xattr_cs |
| ... |
+--------------------+

| block address |

| .i_nid |

SMR stands for "Shingled Magnetic Recording" which makes sense
only for hard disk drives (spinning rust). The ZBC/ZAC standards
enable management of SMR disks, but solid state drives may also
support those standards. So replace "SMR" with "zoned block device"
to avoid a HDD centric terminology.
In particular, rename the HMSMR feature to BLKZONED.

On some systems '/proc/mounts' contains the entry '/dev/root'
as alias for the root device, while that alias doesn't actually
exist as symlink in /dev.
/proc/mounts:
/dev/root / f2fs rw,noatime,background_gc=on,user_xattr,acl,inline_data,extent_cache,active_logs=6 0 0
mount:
/dev/mmcblk1p1 on / type f2fs (rw,noatime,background_gc=on,user_xattr,acl,inline_data,extent_cache,active_logs=6)
If the root device is mounted RO, and we try to scan it, via
'fsck.f2fs /dev/mmcblk1p1', then fsck.f2fs exits because it can't
find the entry in /proc/mounts.
Try harder to identify the root device of the system first, and
in case we are operating on it, check also for '/dev/root' in mounts.

This patch introduces a new option '-p' to do more checks on NAT/SIT areas.
'-p' has 2 levels: level 1 has the same sematics as '-a'; level 2 checks
NAT/SIT counters to see if they matches the status in SB and CP.
A new function, fsck_chk_meta, is called by '-p 1' to implement these
comparsion. If errors are detected, fix_on is set, which means fsck will
do a 'fsck -f' immediately.

SEG_ALIGN, which are both upward. Then, in some extreme scenarios,
such as 16TB, sit_ver_bitmap_bytesize got from segment_count_sit
will exceed MAX_SIT_BITMAP_SIZE, which is calculated in a downward
method.
Unify the two calculating methods and redefine MAX_SIT_BITMAP_SIZE

This tool tries to move the valid blocks ranging from blkaddr to blkaddr + len
to targeted blkaddr with a direction like expand or shrink.
The option includes:
-d debug level [default:0]
-s start block address [default: main_blkaddr]
-l length [default:512 (2MB)]
-t target block address [default: main_blkaddr + 2MB]
-i set direction as shrink [default: expand]
For example,
# defrag.f2fs -s 0x100 -l 0x10 -t 0x4000 /dev/sdb1
This will move data blocks between 0x100 and 0x110 to the right side of
