That is unfortunate.

Sure, I don't think I can argue about it. The current behaviour is a problem,
however, since there is no other way to ensure the system can suspend
reliably but force unmount - we try normal unmount first and proceed with
force if that fails. Do you think that the approach proposed in this patchset
is a reasonable path to mitigate the issue?

Thanks,
Daniil
