[PATCH 00/10] treewide: Fix format strings that misuse continuations

[Joe Perches]

Format strings that are continued with \ are frequently misused.
Change them to use mostly single line formats, some longer than 80 chars.
Fix a few miscellaneous typos at the same time.

Yuck indeed.

I think format strings shouldn't be split across multiple lines and
the right thing to do is to use a single space instead of the tabs.

Fun. I'd done the same grep earlier today. AFAICT you've got all the
ones I had.

If that spacing part is really needed (is it?), wouldn't it be more
readable as:

Also, are there supposed to be tabs in that spacing part?

If it's required (most likely not, but it's a seq_printf and
some people think those should never be modified because it's
a public interface), it should probably be explicit:

" : globalstat %7lu %6lu %5lu %4lu \t\t\t\t%4lu %4lu %4lu %4lu %4lu"

While you are at it, change this to read RTL8187SE, since RTL8180/85
are not supported by this driver.

Yes, would be better. And if it is kept for compatibility it probably 
deserves a comment explaining the weirdness.

Gah, I thought I'd caught most of these when reviewing.  If you're using
a script to pick this stuff up it'd be worth checking for extraneous
continuations in the middle of code - outside of macros there's little
call for it.

Applied, thanks.

Gah, I thought I'd caught most of these when reviewing.  If you're using
a script to pick this stuff up it'd be worth checking for extraneous
continuations in the middle of code - outside of macros there's little
call for it.

Applied, thanks.

There are a few false positives and probably a few missing using

        grep -rP --include=*.[ch] '".*\\$' * | \
        awk '{ if ((gsub("\"", "\"") % 2) == 1) print $0; }'
        
Most of the uses are __asm__ __volatile__ which could be
considered unsightly but don't impact logging messages.

The rest could/should be fixed.

Why?  It's perfectly valid ansi C.

but I also dislike your solution; I'd have split the string into two
separate ones and relied on compiler concatenation.

However, the point is that all three are perfectly legal C.  Choosing
one form over another is something best left to the maintainers rather
than imposing one style by fiat.

Consider this change veto'd unless you can get an explicit ack from the
current maintainer for changing their style.

Because they generally add unwanted spaces or tabs between
words in logging messages.  Just like these do.

Which Linus dislikes because it makes grepping difficult.

Which a patch does not do.

The problem here is not style, but that the whitespace of the indentation
on the second line becomes part of the output!
That makes the code defective and is why Joe posted the patch series.

Hmmm. Would it be an idea to also get rid of all the trailing spaces in the
printks, or is that for another cleanup?

If you'd prefer a separate patch, I can do it.

(cc:s trimmed)

I think it's useful, though like all of these cleanups,
a low priority.  I suggest you submit a few through to
various maintainers and see what happens.

(with false positives for asm and such)
$ grep -rP --include=*.[ch] "\s+\\\n" * | wc -l
7339

There are probably a couple of thousand wasted bytes in
an allyesconfig image and rather more in various logs on
any number of systems.

I'm left with 2303 after cleaning out false positives (of which 1016 in 
staging...).

My point was that it'd be good to also check for just regular use of
continuations in code other than macro definitions.  These are just a
style nit but if there's a script that filters out false positives from
the macros that'd be handy...

> the Blackfin alsa fixes all look good to me, thanks

Running "grep ' \\$' sound/soc/blackfin/*.[ch]" suggests that there's
still some of the continuations I mentioned above in there (plus a lot
of false positives from macros).

Checkpatch is already kind of loud, so I'm not sure I like the idea -
you even say yourself that it's just a style nit.
But just in-case there are a lot of people who do like this, then you
have to do some work to get rid of false positives. Try something like
the following.

1. apply your patch.
2. run something like
find ./ -name "*.[ch]" | xargs ./scripts/checkpatch.pl -f | grep -a3
Continuations

and then go through the results looking for false positives.

One that I see right away, is with #if
For example,

#39: FILE: arch/arm/mach-lh7a40x/lcd-panel.h:39:
+#if defined (MACH_LPD79520)\

WARNING: Continuations outside of macros should be avoided
#40: FILE: arch/arm/mach-lh7a40x/lcd-panel.h:40:

Its syntax is valid but not its semantics.

How about the maintainer takes the fix patch and adjusts style to his
liking?  (That's what I would do because I like fix submissions.)

This is better.

Yeah I am still about, just a lot behind on all things checkpatch.  I am
going to be on a plane in the next couple of days and thats a good time
to get to the checkpatch backlog.
