From 8c39eddbf2842861f6c7412bd498c9d880b1c9e8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Matias=20Bj=C3=B8rling?= Date: Thu, 7 Jul 2016 09:54:18 +0200 Subject: [PATCH] lightnvm: remove unused lists from struct rrpc_block MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The ->list, ->open_list, and ->closed_list lists were previously used for statistics. However, their usage have been removed, and thus these can safely be removed.
