From e7cce77a56bff57144954b8b21fa1e79f00f549e Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Tue, 26 Feb 2013 15:50:22 -0600 Subject: btrfs-progs: initialize save_ptr prior to strtok_r The coverity runs had a false positive complaining that save_ptr is uninitialized in the call to strtok_r. Turns out that under the covers glibc was doing enough to confuse the checker about what was being called. Just to keep the noise down, do a harmless initialization, with a comment as to why.
