> [mtg: ] I'm not sure how to do this but I agree it would be good.  I guess we could have a block of pm_qos requests pre-allocated statically and re-use them.  In practice there will not be more than a handful of requests ever.  Dynamic allocation does seem like a bit of a waste.

The calling code will have to store a pointer to your structure
anyway, you may as well have them provide the whole structure.
