I don't want to drag this thread onwards for (way) too long, but clearly "it is
advised to indent labels with a single space (not tab)" (from diff in above commit)
doesn't really reflect the majority of kernel practice we have in-tree today and
actually rather adds more confusion than any clarification whatsoever:

$ git grep -n "^\ [a-z_]*:" -- '*.[ch]' | wc -l
4919
$ git grep -n "^[a-z_]*:" -- '*.[ch]' | wc -l
54686

A CodingStyle document should document what's regarded as a general consensus of
kernel coding practices, and thus should represent the /majority/ of coding style,
which (if I didn't screw up my git-grep line completely) above 9% does not really
reflect at all. So, new folks starting with kernel hacking reading this are rather
misguided, and code-wise it just adds up to have more inconsistencies from new
patches, or worse, have noisy patches (like this one) flying around that try to
brute-force everything into this advice.
