You might try something with clang-format.  It doesn't have a built-in 
style option for the kernel (probably because the kernel can't currently 
be compiled with Clang/LLVM, but Linux does qualify for the first two 
criteria for having a new style default added, so if someone wants to 
actually work on it, they could probably get it included), but something 
like this for the config should get you pretty close:


BasedOnStyle: LLVM
IndentWidth: 8
UseTab: Always
BreakBeforeBraces: Linux
AllowShortIfStatementOnASingleLine: false
IndentCaseLabels: false

I'm pretty certain that this doesn't cover everything from CodingStyle, 
but it should cover most things, and most of the other stuff should be 
relatively easily scriptable using regex based replacements.

Yes, I just tried `scripts/Lindent` and it has the same problem.

I had compared the source of `Lindent` with `-linux` option of

Huh?

CodingStyle says:

  Now, again, GNU indent has the same brain-dead settings that GNU emacs
  has, which is why you need to give it a few command line options.

It also says try using scripts/Lindent.  Have you tried it?
It won't be perfect either, AFAI recall, but it might help.

or you could try emacs (as indicated in CodingStyle).  Good luck with that.

Indent issus in kernel module development

[chunguang qu]

`indent -linux` sometimes made my code totally a mess.
I know it most likely a bug of GNU INDENT. And this is not a bug report.
I only want to know other kernel developers how to deal with this problem.
Since GUN INDENT is recommend in kernel's CodingStyle, I think surely
someone here encounter this problem either.
