:resend that I mistakenly sent only to Mark, with a couple more comments

I disagree.

Look at the long line wrapping style of the rest of the file
and most of the kernel source.  No additional arguments to
functions are generally used after column 80.

If it's ever agreed that all lines > 80 cols are OK or
new args after column 80 are OK, then sure.  Until then,
if you want it, you should do it.

cheers, Joe

It's been already agreed they are OK for any code.

It's a runtime bug.  Are "code nannies" supposed to "try" to fix
runtime bugs in libata while others just sit there and insult them?

Nope, I'm just the guy that identified the defect
and proposed a patch.  You can fix it differently
if you want.  Jeff could fix it differently as well.
I don't care that much.  I don't own a device that
uses this controller.  I'll never see the message.
Perhaps no one ever will.

Maybe Sergey Matyukevich, the original author, wants
to fix it up in another way.

Oh, there's a service affecting bug there?
Well, I guess that means we should accept a shoddy patch, then.  :)

But seriously, I didn't mean anything bad by it, just that
it ought to be simple for the original sender to just reformat it
and resubmit.  Just like everyone else here does on a daily basis.

No point in making the code harder to read/understand for no good reason.

But if these patches are robot generated (by a code scan tool or something),
then the original sender (Joe) might have many others in the queue
throughout the kernel, which could explain the reluctance here.

Really, though the best solution would be for Jeff to just edit
that one line as he integrates the patch, like Linus would do.
I imagine Jeff's already done that by now.  ;)

In case you missed it, it *has* already been "agreed" that
there's nothing magical about 80 anymore.

Please don't bother with that insane "line length" option when using 
"--file". At least not if the "fix" is to just mindlessly split the line. 
That is _never_ a fix.

Changes like these:

just make the code harder to 'grep'.

Yes, at some point you have to split lines, but that point is not 80
columns any more.  The advantage of getting the whole line when grepping
for function names much outweighs the downside of somebody using those
old 80x24 green phosphorous vt52's.

[ The same thing very much goes for complex if-statements etc.  If
  people can't stand the long lines, the primary solution would be to
  turn a complex conditional into a helper inline functions, or to fix
  excessive indentation by splitting up functions.

  In the above case, the last one could perhaps have been handled
  creating a new variable for and moving the cast to the initialiser,
  for example. Is it worth it to avoid a 85-column line? Probably not.

  And some lines just end up long.  I think 100 characters may be a
  more reasonable limit for "too long", but quite frankly, it depends on
  the line.

  So I think 'checkpatch' is pure crap in this area, and I've told
  people so before, and they keep telling me that it has relaxed it's
  idiotic warnings, but that is apparently just a lie. ]

Oh well.  If I actually read perl, I could parse what the hell those
80-character rules are in checkpath.  It already has random "it's ok if
X" stuff.  But it never seems to really have any "oh, but splitting is
worse" logic.
