From 75df023f4f2188c21181996e28234fef9351ef45 Mon Sep 17 00:00:00 2001 From: Guoqing Jiang Date: Fri, 24 Feb 2017 11:15:13 +0800 Subject: md-cluster: remove useless memset from gather_all_resync_info This memset is not needed. The lvb is already zeroed because it was recently allocated by lockres_init, which uses kzalloc(), and read_resync_info() doesn't need it to be zero anyway.
