One issue with that appears to be checking permissions. AFAIU this
patchset only enables the optimization if default_permissions is
turned off (i.e. all permission checking is done by the server). But
virtiofs uses the default_permissions model.

I'm not quite sure about this limitation, guessing that it's related
to the fact that the permissions may be stale at the time of checking?

Thanks,
Miklos
