And yet your solution to that is to ... do all your work in the kernel space and declare the tooling as something that does not interest you? ;-) > Something I've wanted for a long time is to port kvm_stat to use tracepoints > instead of the home-grown instrumentation.

So which one is it, KVM developers are volunteers that do fun stuff and cannot be told about project priorities, or KVM developers are pros who do unfun stuff because they can be told about priorities? I posit that it's both: and that priorities can be communicated - if only you try as a maintainer. All i'm suggesting is to add 'usable, unified user-space' to the list of unfun priorities, because it's possible and because it matters.
