From 65e99c43e9c2fee1a1f02c100154730fbeae9717 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Wed, 4 Sep 2019 20:22:39 +0300 Subject: btrfs: Don't assign retval of btrfs_try_tree_write_lock/btrfs_tree_read_lock_atomic Those function are simple boolean predicates there is no need to assign their return values to interim variables. Use them directly as predicates. No functional changes.
