From 0a1e8258a4fecd5aad2815b43bbe0ff014de1d8a Mon Sep 17 00:00:00 2001 From: Chengguang Xu Date: Mon, 10 Dec 2018 00:22:38 -0500 Subject: ext4: compare old and new mode before setting update_mode flag If new mode is the same as old mode we don't have to reset inode mode in the rest of the code, so compare old and new mode before setting update_mode flag.
