From 66253a818362601c00c4b98715bd819940075937 Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Wed, 14 Aug 2013 16:16:40 -0700 Subject: [PATCH] btrfs-progs: fix qgroup realloc inheritance qgroup.c:82:23: warning: memcpy with byte count of 0 qgroup.c:83:23: warning: memcpy with byte count of 0 The inheritance wasn't copying qgroups[] because a confused sizeof() gave 0 byte memcpy()s. It's been like this for the year since it was merged, so I guess this isn't a very important thing to do :).
