From 5c9a702ed1724f1c856c7299fe1faf9b3b5b4eb0 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Fri, 1 Dec 2017 11:19:40 +0200 Subject: [PATCH] btrfs: Remove unused variable in btrfs_get_extent trans was statically assigned to NULL and this never changed over the course of btrfs_get_extent. So remove any code which checks whether trans != NULL and just hardcode the fact trans is always NULL.
