But it's still being used in quite hot paths (pipe, splice, socket) and I don't really wanna mix up a change which can cause subtle scheduling related performance regression into this patch. How about using the dummy waitqueue hack for now and when removing the @sync param, switch it to one of wakeup APIs? I'll be happy to add big /* TODO */ comment in the function.
