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 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.

Since f2fs support large sector size in commit 55cf9cb63f0e "f2fs: support large
sector size", block device with sector size of 512/1024/2048/4096 bytes can be
supported.
But mkfs.f2fs still use default sector size: 512 bytes as sector size, let's fix
this issue in this patch.
v2:
o remove unneeded printed message when sector size is large than 512 bytes
suggested by Kinglong.
o show correct sector size in printed message.
o use config.sectors_per_blk instead of DEFAULT_SECTORS_PER_BLOCK suggested by
Kinglong.

o remove another unneeded printed message when sector size is large than 512
bytes suggested by Kinglong.

I might found a bug in mkfs.f2fs. while experimenting with f2fs on my big
endian MIPS32 device (platform lantiq, 14.07-rc3, uclibc).
I ran into an issue that mkfs.f2fs, was not able to format block devices if I
did not specify the sector count manually.
I hunted it down to lib/libf2fs.c.
After I found that the detected sector count equals to the wanted sector count
shifted left (32+9) times.
I found two issues:
Firstly it uses ioctl BLKGETSIZE, which writes to an uint32_t the size of the
device.
As c->total_sectors is of type uint64_t, the value is written in to the first
4 bytes.
That explained the left shift of 32 bits.
Secondly BLKGETSIZE determines the size of the device in bytes (AFAIK, learned
by observation).
In the first branch of the if-block patched below, the c->total_sectors is
calculated by
c->total_sectors = stat_buf.st_size / c->sector_size;
The else branch omits the devision. sector_sice is mostly 512, that explained
the left shift by 9 bytes.
* fixes sector count calculation
* uses BLKGETSIZE64 if avail
