Re: [PATCH v2 03/12] f2fs: cache: introduce shrinker

Hi Chao,

and the scan path includes:

> 					nr_to_scan - freed);

The count path includes the meta and node caches, while the scan path also
includes `COMPRESS_CACHE`.

Is `COMPRESS_CACHE` intentionally excluded from `__count_cache()` even though
`f2fs_shrink_cache()` scans it?
