From 408fbf19ad78d8ab0656289efea77c10a342f043 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Thu, 27 Jul 2017 14:37:29 +0300 Subject: btrfs: Remove extraneous chunk_objectid variable BTRFS_FIRST_CHUNK_TREE_OBJECTIS id the only objectid being used in the chunk_tree. So remove a variable which is always set to that value and collapse its usage in callees which are passed this variable.
