From 2f8c9011151337d0bc106693f272f9bddbccfab2 Mon Sep 17 00:00:00 2001 From: Vishal Verma Date: Wed, 27 Feb 2019 17:06:26 -0700 Subject: [PATCH] libnvdimm/btt: Remove unnecessary code in btt_freelist_init We call btt_log_read() twice, once to get the 'old' log entry, and again to get the 'new' entry. However, we have no use for the 'old' entry, so remove it.
