IIRC Sakari has at some point the series converted yesno and Co. to something which I don't remember the details of. Guys, what do you think?

I like your version, but here we also discussing a possibility to do something like %py[DOY].

Honestly, I think that yesno() is much easier to understand than %py. And %py[DOY] looks really scary. It has been suggested at https://lore.kernel.org/lkml/YCqaNnr7ynRydczE@smile.fi.intel.com/#t Yes, enabledisable() is hard to parse but it is still self-explaining and can be found easily by cscope. On the contrary, %pyD will likely print some python code and it is not clear if it would be compatible with v3. I am just kidding but you get the picture. Best Regards, Petr

Personally I prefer %s and the functions. I think the format specifiers have become unwieldy. I don't remember any of the kernel specific ones by heart, I always look them up or just cargo-cult. I think the fourcc format specifiers are a nice cleanup, but I don't remember them either. I'd like something like %foo{yesno} where, if you remember the %foo part, you could actually also remember the rest. But really if you get *any* version accepted, I'm not going to argue against it, and you can disregard this as meaningless bikeshedding. BR, Jani.

Consolidate yesno() helpers under string.h hood. I was taking a look on i915_utils.h to reduce it and move some of it elsewhere to be shared with others. I was starting with these helpers and had [1] done, then Jani pointed me to this thread and also his previous tentative. I thought the natural place for this would be include/linux/string_helpers.h, but I will leave it up to you. After reading the threads, I don't see real opposition to it.
