From 4bcfcb47faaf1adc912be64892e01b92b377c8c5 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 27 Feb 2014 10:25:49 -0500 Subject: Btrfs-progs: make sure to save mirror_num only if it is set If we are cycling through all of the mirrors trying to find the best one we need to make sure we set best_mirror to an actual mirror number and not 0. Otherwise we could end up reading a mirror that wasn't the best and make everybody sad.
