I'm experimenting with using the generic bool type and using sparse I

I'm not really worried about this, I assume that sparse hasn't caught
up with what bool really means, but perhaps this can be looked into by
someone who knows sparse well. The warnings don't really add up and
with more people switching to use the generic bool this may beceome
unwanted.

Actually, I am "assigned" to that. :)
ah cool
Just out of curiousity, where do you see those messages? In the log for
allyesconfig on i386 I only found ntfs/super.c with similar output.
I was poking around replacing the boolean_t typedef in e1000, so it's nothing
upstream. Just run `sed -i s/boolean_t/bool/g` on all the files in
drivers/net/e1000 to see :)
the version of sparse is that in fc6, so that may be out-of-date (?).
alternatively we might need to reconsider the `typedef _Bool bool;`
declaration and force it to be unsigned. I'm not sure what to think of
that.
I do not see how that would make any sense.
well the sparse warning is about signedness. Either sparse needs to "know" that
bool is unsigned, or the kernel headers need to somehow make bool unsigned...
the latter choice would come down to just that, but it doesn't look like a good
idea to me either somehow.
