Hi David.

It might be better if you would submit patches
to checkpatch before you nack others.

How about you track the --- and +++ lines and
submit a suggested patch yourself?

Just as there's nothing wrong with storing original
and modified versions of subdirectories too.

There's no single perfect test and it's just a silly
warning anyway.

I think the most common case is the direct editing of
a single file and production of a diff to submit as
a patch.
 
$ emacs <file>
# make changes, save original as ~ backup
$ diff -urN <file>~ <file> > ./foo.diff
$ make mrproper; make allyesconfig ; make
# deletes backup files
$ ./scripts/checkpatch.pl foo.diff

I didn't bother even finding out why the message
was emitted for me even though I had a b temp
directory in my tree.  I just ignored it.

cheers, Joe
