From 18cc980ac8cf8c727d1f7d581b4576ed64bd78a6 Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Wed, 18 Mar 2015 18:59:02 -0400 Subject: [PATCH] dm log userspace base: fix compile warning This fixes up a compile warning [-Wunused-but-set-variable] - given the comment in userspace_set_region_sync() the non-reporting of errors is intentional so the return value can be dropped to make gcc happy. Also, fix typo in comment.
