Hi,

Well, the checkpatch.pl reports were all style (and mostly whitespace);

kernel, and I adjusted the few I found (and sent changes upstream).

style matters, as it's a thing with your brain. You learn patterns and
if the patterns change, you have to do more work and don't see the real
issues involved. So by ignoring our style you are saying you don't want
anyone else in the kernel community to ever review or work on the code,
which isn't ok.

Looks like I can't side step this unless Hans is willing to shift the
usbredir project entirely to using kernel style :-/.

I'm fine with moving the usbredir project to the kernel style, the question
is how to do this without causing any hidden breakage.

Can you create a gnu-indent invocation which will do most of the work?

And then a hopefully managable sized patch on top to fix the remaining
style errors in usbredirparser ?

I will plan to make changes so that checkpatch runs clean; I lay out my
concerns and my plan below to make sure I'm taking the best path.

My main concern with changing the ~2,500 lines of code from the upstream
usbredir project is that it will increase the odds that I will introduce
errors, both initially, and again later as I review and attempt to relay
patches from the upstream.

To summarize the checkpatch reports: the biggest issue is whitespace,
which shouldn't be a problem; I should be able to automate that without
error. There are also a fair number of one offs; FSF address, space
after '!', etc. I hope to persuade Hans to take a few style only
patches upstream to address those. That leaves a pack of about 60 brace
placement and line length issues.

I will plan to manually change those prior to submission. Any upstream
changes that affect the same code will be manually corrected as well,
prior to submission.

Make sense?

Sounds good, note that as said I'm fine with moving over the usbredir(parser)
code to the kernel style, as long as the changes are reviewable.

I think it may be best to only convert the usbredirdparser files, as those
are the only ones you need for the kernel. Having a mixed style in usbredir
is not ideal, but something I can live with.

Regards,

Hans
