Subjectsmatch_scripts/whitespace_only.sh
I wrote a script to check that a patch only changes white space.
It compiles the files before and after the patch is applied and
verifies that they are the same.

You'll need to compile smatch:
git pull git://repo.or.cz/smatch.git
make
cd /path/to/kernel/src/
/path/to/smatch_scripts/whitespace_only.sh <patch>

Adding or removing parenthesis and curly braces counts as a code
change. Changes to comments, #if 0, white space changes do not.

You can fix a lot of style violations if you limit yourself to
adding and removing tabs, spaces and new lines. Then the next
patch could remove unneeded parenthesis. It would be easier to
audit that way instead of everything mixed together.

dan carpenter

PS. I feel really bad slagging the newbies trying to help.
Could we fix checkpatch.pl to not complain about line lengths?
Also could we tell them to stay in staging where no one cares
about git blame?
