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.
