From d98a5ffe6f33d4039bf2f60dcd1fc121771d7cbc Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Wed, 26 Feb 2014 16:23:08 +0800 Subject: [PATCH] btrfs-progs: Init root_item to avoid gcc 4.8.2 warning When using gcc 4.8.2, -Wmaybe-uninitialized will report root_item may be used uninitialized. Since root_item_valid variant is used to determine the root_item valid, it's a false alert and to avoid the warning, just init it on allocation.
