Hello Juergen,


I've started to work on checkpatch-like python script. I make i= t based on  clang-format-diff.py and it works as pre-commit hook.=

I will follow this approach.

It seems like specific script for style checking is not needed. Because cla= ng-format tool does style checking by itself.
All we need is just to provide appropriate coding style description file fo= r each.
Clang-format is a bit specific tool, so we can not specify explicitly file with coding st= yle description.
It just looks for a .clang-format file in one of a parent directories of a file b= eing checked.
As we got at least three coding-styles we = have to substitute needed file in sources top directory for each check.
It could be done by generat= ing .clang-format file dynamically depending on style= /path from the STYLES file.
Another way could be using appropriate symlink on existing .clang-format= file which is located somewhe= re in  tools/clang-format= /coding-style-file like:
tools/clang-format/xen-style
tools/clang-format/linux-style<= /div>
tools/clang-format/xl-style
