I agree that empty structs are useful, but here we are talking about per-CPU variables only, which is the first use case so far, as far as I can see. If we had pahole 1.22 released and widely packaged it could have been a viable option to force it on everyone.
... Would it be feasible to put the sources for pahole into the kernel repository and build it at the same time as objtool? That would remove any issues about the latest version not being available.
