+Subject: [PATCH] libmount: use eacess() rather than open() to check mtab/utab
+
+The open() syscall is probably the most strong way how to check write
+accessibility in all situations, but it's overkill and on some
+paranoid systems with enabled audit/selinux. It fills logs with
+"Permission denied" entries. Let's use eaccess() if available.
