From 2510307e6c78d1d9a59c85164cbff66f8a9f3fed Mon Sep 17 00:00:00 2001 From: David Sterba Date: Wed, 2 Oct 2019 01:08:03 +0200 Subject: [PATCH] btrfs: compression: inline cleanup_workspace_manager Replace loop calling to all algos with a list of direct calls to the cleanup manager callback. When that becomes trivial it is replaced by direct call to the helper.
