From 9102adcbc8521dfee5da2fd86b6f8333ee89f3d8 Mon Sep 17 00:00:00 2001 From: Rakesh Pandit Date: Sat, 19 Apr 2014 14:12:03 +0300 Subject: [PATCH 08/42] Btrfs-progs: fi usage: free memory if realloc fails Lets not assign *info_ptr to 0 before calling free on it and lose track of already allocated memory if realloc fails in add_info_to_list. Lets call free first.
