From 15b2ae776044ac52cddda8a3e6c9fecd15226b8c Mon Sep 17 00:00:00 2001 From: Kari Argillander Date: Tue, 7 Sep 2021 18:35:57 +0300 Subject: [Backport 15b2ae776044] src: Show uid/gid always in show_options() Show options should show option according documentation when some value is not default or when ever coder wants. Uid/gid are problematic because it is hard to know which are defaults. In file system there is many different implementation for this problem. Some file systems show uid/gid when they are different than root, some when user has set them and some show them always. There is also problem that what if root uid/gid change. This code just choose to show them always. This way we do not need to think this any more.
