Subject[f2fs-dev] [PATCH v2] f2fs: fix wrong statistics of inline data
Date
If we remove a file that has inline data after mount, our statistics turns to
inaccurate.

cat /sys/kernel/debug/f2fs/status
- Inline_data Inode: 4294967295

Let's add stat_inc_inline_inode() to stat inline info of the file when lookup.

Change log from v1:
o stat in f2fs_lookup() instead of in do_read_inode() for excluding wrong stat.
