From 9a37d02c497cd839beee3e0cab0fc606bcfe08bf Mon Sep 17 00:00:00 2001 From: Jason Yan Date: Fri, 10 Mar 2017 11:49:12 +0800 Subject: [PATCH] md: fix incorrect use of lexx_to_cpu in does_sb_need_changing commit 1345921393ba23b60d3fcf15933e699232ad25ae upstream. The sb->layout is of type __le32, so we shoud use le32_to_cpu.
