Re: [PATCH v2 05/12] f2fs: cache: use meta cache

Hi Chao,

and in `f2fs_sync_meta_caches()`:

> 	break;

`adjust_flush_cache_number()` returns `BIO_MAX_VECS` for META, while
`nwritten` advances by `sbi->blocksize` for each entry before the comparison.

Are `nr_to_write` and `nwritten` intended to be entry counts or byte counts in
this path?
