    SubjectRe: [PATCH 6/6] mce-inject: use injected mce only during faked handler call

    Correct. The fixes are beyond what we can do in .32 - and for .33 i
    outlined (with a patch) that we should be using not just the ftrace
    ring-buffer (like your patch did) but perf events to expose MCE events.

    That brings MCE events to a whole new level of functionality.

    Event injection support would be an interesting new addition to
    kernel/perf_event.c: non-MCE user-space wants to inject events as well -
    both to simulate rare events, and to define their own user-space events.

    Is there any technical reason why we wouldnt want to take this far
    superior approach?
