From 29c87793eb3c6f78f215f85be863e5415e263e43 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 29 Mar 2022 16:27:21 -0400 Subject: f2fs: Get the superblock from the mapping instead of the page It's slightly more efficient to go directly from the mapping to the superblock than to go from the page. Now that these routines have the mapping passed to them, there's no reason not to use it.
