From 08b0b0059bf1c2e8637f724cc7cc4d29b1e808de Mon Sep 17 00:00:00 2001 From: Matthew Wilcox (Oracle) Date: Wed, 16 Dec 2020 11:06:33 -0500 Subject: mm: Add flush_dcache_folio() This is a default implementation which calls flush_dcache_page() on each page in the folio. If architectures can do better, they should implement their own version of it.
