    SubjectRe: [PATCH 11/18] i915: Provide config option for enabling tracepoints
    Out of curiosity what motivated this patch? When adding the tracepoints,
    I found the overhead of compiling in but not enabling them to be
    insignificant, i.e. nearly unmeasurable in throughput benchmarks, so
    didn't believe it warranted a config option. Especially one that advises
    people to turn off what may be a useful aid in desktop systems.

    Also is TRACER the right name, that would seem to confuse the option with
    a standalone tracer as opposed to simply enabling tracepoints.
