mm/fs: convert inode_attach_wb() to take a folio
Patch series "Writeback folio conversions".
Remove more calls to compound_head() by passing folios around instead of
pages.
This patch (of 2):
The only caller of inode_attach_wb() which doesn't pass NULL already has a
folio, so convert the whole call-chain to take folios.
