Hi, I sent the following to help-gnu-emacs and got no reply, maybe this 
list is more relevant.

Hello list,

is the "linux" c-style supposed to be compliant to the linux kernel style 
guidelines? I just realised that all this time emacs was indenting my code 
slightly wrong, specifically the use of spaces is forbidden, even when 
continuing the argument list of a function.

I use the following lines in my .emacs, taken from Documentation/CodingStyle of 
the kernel tree. Perhaps they should be added to "linux" style?


(defun c-lineup-arglist-tabs-only (ignored)
   "Line up argument lists by tabs, not spaces"
   (let* ((anchor (c-langelem-pos c-syntactic-element))
	  (column (c-langelem-2nd-pos c-syntactic-element))
	  (offset (- (1+ column) anchor))
	  (steps (floor offset c-basic-offset)))
     (* (max steps 1)
        c-basic-offset)))

;; Add kernel style
(c-add-style
  "linux-tabs-only"
  '("linux" (c-offsets-alist
	     (arglist-cont-nonempty
	      c-lineup-gcc-asm-reg
	      c-lineup-arglist-tabs-only))))

(custom-set-variables
 '(c-default-style "linux-tabs-only")
)


Thanks,
Dimitris
