We obviously disagree on the benefit.  Before this series, error
reporting is *broken* for QMP.  Fixing that is definitely not "why
bother" material.

I certainly don't object to tightening our testing habits.  I was merely
pointing out that you're doing that.

Testing patches that modernize interfaces often isn't easy for the
person doing the work.  Fortunately, megasas has a maintainer: Hannes.
Who gave his R-by.  For me, that would suffice, but you may see things
differently.  Would a Tested-by from him satisfy you?  If not, what
would satisfy you?
