From e9ebecf266c6657de5865a02a47c0d6b2460c526 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 24 Mar 2023 18:01:29 +0000 Subject: [PATCH] ext4: Use a folio in ext4_read_merkle_tree_page This is an implementation of fsverity_operations read_merkle_tree_page, so it must still return the precise page asked for, but we can use the folio API to reduce the number of conversions between folios & pages.
