From 21e75ffe3cd2c99ca4ea5ecb25dcbeb6a8024c30 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Wed, 15 Feb 2017 16:28:32 -0500 Subject: btrfs: btrfs_truncate_free_space_cache always allocates path btrfs_truncate_free_space_cache always allocates a btrfs_path structure but only uses it when the caller passes a block group. Let's move the allocation and free into the conditional.
