From f67d922edb4e95a4a56d07d5d40a76dd4f23a85b Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Wed, 22 Nov 2023 12:17:37 -0500 Subject: fs: indicate request originates from old mount API We already communicate to filesystems when a remount request comes from the old mount API as some filesystems choose to implement different behavior in the new mount API than the old mount API to e.g., take the chance to fix significant API bugs. Allow the same for regular mount requests.
