Subject: [PATCH] [QUESTION] ext4: Why does fsconfig allow repeated mounting?
Date: Tue, 10 Feb 2026 01:01:48 +0800	[thread overview]
Message-ID: <20260209170148.12688-1-oaygnahzz@gmail.com> (raw)

Hi all,
The mount interface will report an error for repeated mounting,
but fsconfig seems to allow this. Why is that?

Thanks.
