From c39aa7056f50fa7b49265ea35c0f3eddb7c7be68 Mon Sep 17 00:00:00 2001 From: Sergey Senozhatsky Date: Wed, 25 Jun 2014 00:00:44 +0900 Subject: [PATCH] btrfs compression: reuse recently used workspace Add compression `workspace' in free_workspace() to `idle_workspace' list head, instead of tail. So we have better chances to reuse most recently used `workspace'.
