+Subject: [PATCH] libmultipath: fix files read from config_dir
+
+If config_dir contains a file named, for example, "some.conf.backup", this file
+will still be loaded by multipath because process_config_dir()
+(libmultipath/config.c) uses strstr() to check for the ".conf" extension, but
+that doesn't guarantee that ".conf" is at the end of the filename.
+
+This patch will make sure that only files ending in ".conf" are loaded from
+config_dir.
+
+This is to comply with config_dir entry description in man 5 multipath.conf.
