From d3fac6ba7dccc54f52087bb9d7b9be27aa6fa622 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Tue, 24 Oct 2017 11:50:39 +0300 Subject: [PATCH] btrfs: Remove redundant mirror_num arg The following callpath is always invoked with mirror_num set to 0, so let's remove it as an argument and directly pass 0 to __do_redpage.
