From 1c7c01420d592e0e87e532ac688e61d5a2fafab2 Mon Sep 17 00:00:00 2001 From: Larry Dewey <ldewey@suse.com> Date: Thu, 9 Jan 2020 14:36:45 -0700 Subject: [PATCH] libfs: Fixing issue with variable name collision Due to the structure of the old code, variable name collisions were occuring when building with the `-fno-common` flag. These changes fix the problem.
