If f2fs_iget cannot search inode from inode cache, it will read
the inode from disk. The processing of read from disk and init inode
should not dirty the inode, as the commit 530e07042002 ("f2fs:
don't mark compressed inode dirty during f2fs_iget()").
Thus, we can remove the unnecessary f2fs_inode

We have define 'fi' at the begin of the functions, just use it,
rather than use F2FS_I(inode) again.

Almost all other initialization of variables in f2fs_fill_super are
extraced to a single function. Also do it for write_io[], which can
make code more clean.
This patch just refactors the code, theres no functional change.

For now, f2fs use mount options 'fault_injection' and 'fault_type'
to enable fault injection. We set inject_type and inject_rate in sysfs
to control fault injection.
In fact, common fault injection framework have provided a systematic
way to support error injection via debugfs, which has more rich
Then, we don't need to depend on CONFIG_F2FS_STAT_FS to create
f2fs root debugfs directory /sys/kernel/debug/f2fs.
This patch is prepared for following f2fs fault injection,
which will create sub directory 'fault_inject' into f2fs root debugfs.

Hi,
Kernel fault injection framework have provided a a systematic
way to support error injection via debugfs in the /sys/kernel/debug
directory.
Compared to the current fault injection by mount options and sysfs,
fault injection framework can provide more easy used fault injection
