It's possible to trigger the block device autoloading mechanism with a mknod()/stat(), and this mechanism has long been declared obsolete, thus triggering a dmesg warning since el9_7, which then fails the test. You may need to `rmmod loop` to reproduce. Avoid this by avoiding to trigger a loop autoload - we just make a different blockdev. Chosing `42` here should avoid any autoload mechanism as this number is explicitly for demo drivers and should never trigger an autoload. We also just ignore the warning line in dmesg. Other tests can and might perhaps still trigger this, as well as background noise running during the test. Signed-off-by: Auke Kok <auke.kok@versity.com>
