[PATCHv7 2/6] iomap: Move folio_detach_private() in iomap_iop_free() to the end

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

 



In later patches we will add other accessor APIs which will take inode
and folio to operate over struct iomap_page. Since we need folio's
private (iomap_page) in those functions, hence this function moves
detaching of folio's private at the end just before calling kfree(iop).
