This patch changes the naming of orphan-related data structures to use as
inode numbers managed globally.
Later, we can use this facility for managing any inode number lists.

The stat_show is just to show the current status of f2fs.
So, we can remove all the there-in locks.

This patch removes a bitmap for victim segments selected by foreground GC, and
modifies the other bitmap for victim segments selected by background GC.
1) foreground GC bitmap
: We don't need to manage this, since we just only one previous victim section
number instead of the whole victim history.
The f2fs uses the victim section number in order not to allocate currently
GC'ed section to current active logs.
2) background GC bitmap
: This bitmap is used to avoid selecting victims repeatedly by background GCs.
In addition, the victims are able to be selected by foreground GCs, since
there is no need to read victim blocks during foreground GCs.
By the fact that the foreground GC reclaims segments in a section unit, it'd
be better to manage this bitmap based on the section granularity.

As the "status" debugfs entry will be maintained for entire F2FS filesystem
irrespective of the number of partitions.
So, we can move the initialization to the init part of the f2fs and destroy will
be done from exit part. After making changes, for individual partition mount -
entry creation code will not be executed.

There is an race condition between umounting f2fs and reading f2fs/status, which
results in oops.
Fox example:
Thread A Thread B
umount f2fs cat f2fs/status
f2fs_destroy_stats() { stat_show() {
list_for_each_entry_safe(&f2fs_stat_list)
list_del(&si->stat_list);
mutex_lock(&si->stat_lock);
si->sbi = NULL;
mutex_unlock(&si->stat_lock);
kfree(sbi->stat_info);
} mutex_lock(&si->stat_lock) <- si is gone.
...
}
Solution with a global lock: f2fs_stat_mutex:
Thread A Thread B
umount f2fs cat f2fs/status
f2fs_destroy_stats() { stat_show() {
mutex_lock(&f2fs_stat_mutex);
list_del(&si->stat_list);
mutex_unlock(&f2fs_stat_mutex);
kfree(sbi->stat_info); mutex_lock(&f2fs_stat_mutex);
} list_for_each_entry_safe(&f2fs_stat_list)
...
mutex_unlock(&f2fs_stat_mutex);
}

This patch should resolve the bugs reported by the sparse tool.
Initial reports were written by "kbuild test robot" managed by fengguang.wu.
In my local machines, I've tested also by running:
> make C=2 CF="-D__CHECK_ENDIAN__"
Accordingly, I've found lots of warnings and bugs related to the endian
conversion. And I've fixed all at this moment.

This moves all of the f2fs debugging files into debugfs. The files are
located in /sys/kernel/debug/f2fs/
Note, I think we are generating all of the same information in each of
the files for every unique f2fs filesystem in the machine. This copies
the functionality that was present in the proc files, but this should be
fixed up in the future.
