From 29c5e5d4966d8d56e18e008da01108167d8d6fd1 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 28 Aug 2018 14:21:01 +0100 Subject: [PATCH] btrfs: remove unused pointer 'tree' in btrfs_submit_compressed_read Pointer 'tree' is being assigned but is never used hence it is redundant and can be removed. This is a leftover from cleanup patch 00032d38eaa89c76de7 ("btrfs: drop extent_io_ops::merge_bio_hook callback").
