[RFCv2 2/5] ext4: Remove PAGE_SIZE assumption of folio from mpage_submit_folio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



mpage_submit_folio() was converted to take folio. Even though
folio_size() in ext4 as of now is PAGE_SIZE, but it's better to
remove that assumption which I am assuming is a missed left over from
patch[1].
