But that's just how I operate. Ask Thomas Gleixner. Every single hrtimers/nohz bug I've found on sparc64, I sent him either a full fix or a full analysis of the bug and a description of exactly what is going on and what needs to be changed so he can compose the bug fix patch with minimal effort. I don't ask people to revert, ever. It's never necessary when the parties involved are extremely competent and responsive.
