Subject: [PATCH 4.19 07/71] btrfs: Move free_pages_out label in inline extent handling branch in compress_file_range

From: Nikolay Borisov <nborisov@...e.com>

[ Upstream commit cecc8d9038d164eda61fbcd72520975a554ea63e ]

This label is only executed if compress_file_range fails to create an
inline extent. So move its code in the semantically related inline
extent handling branch. No functional changes.
