From 63709fd4296221aa4ebd06230bce3eed70ddd927 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 16 Jun 2017 21:13:38 +0300 Subject: [PATCH] uuid: Take const on input of uuid_is_null() and guid_is_null() The null check functions do not and must not modify contents of the UUID or GUID supplied. Mark argument explicitly to reflect that.
