Joe,
I think most of the offenders were caught back in late 2009.
I found a couple old patches that I submitted back then that were never acked
so I just updated and reposted them.
Also, I have never looked at coccielle... ;-)
Regards,
Hartley

Done via coccinelle script:

- ptr->end - ptr->start + 1

Mostly uncompiled, not enough cross-compilers.

If you put parentheses, it will consider removing them. But I don't think
it would go the other way around.

And no reply on my patch for this one.
Your treewide patch can be used instead of my individual patches if it's
easier/cleaner.

Yup.
There are also several uses of struct resource var;
var.end - var.start with or without +1.
I'm going through them now and will resubmit.
Several fixes as well where the +1 was missing.
Done via coccinelle scripts like:
@@
struct resource *ptr;
@@
- ptr->end - ptr->start + 1
+ resource_size(ptr)
and some grep and typing.
Mostly uncompiled, no cross-compilers.
Some checkpatch complaints cheerfully ignored.

Hi Joe,
thanks a lot for the patch. I will be happily taking it. However it seems
like some of the files are going away/have been moved in -next. Could you
please respin on top of what is still applicable on -next and resend?
Thanks,

Hi Jiri.
The original patch is for next-20110607.
There were 2 identical patches for resource_size
applied to the next tree as of next-20110609.
I just cherry-pick'ed it and the diff is the same
modulo those 2 already applied bits.
Because it's pretty large, I'll send the new diff
just to you off-list.
cheers, Joe
