Hi, please comment on this patch. It is against 2.6.7

Description: removes check_region call from specialix.c and cleans
up some debug print messages and some dead code.

Looks good.  As far as I can tell, you removed the only call to
sx_check_io_range(), but didn't remove the function itself.  Doesn't gcc
warn about functions declared static but never called?  Or is this
different because it's also marked inline?

the nation that is attacked, and every man will be glad of those

to examine any refutations of them; and thus he will by and by convince 
himself that the war is just, and will thank God for the better sleep 
he enjoys after this process of grotesque self-deception." -- Mark Twain

[Kristen Carlson]

[-- Attachment #1: Type: text/plain, Size: 9746 bytes --]

Not sure on the gcc question, but it makes no sense to keep dead code
around, so here is another patch that is exactly the same, but removes
the inline function.

Description: remove check_region from specialix.c plus cleanup dead code
and debug prints

Re: [Kernel-janitors] [PATCH] remove check_region specialix

[Michael Veeck]

[-- Attachment #1: Type: text/plain, Size: 10836 bytes --]

Read Documentation/SubmittingPatches and you'll find that you should 
diff one level up from the linux-source-dir.

Thanks!  For my benefit, what's the easiest way to check for trailing spaces?
I thought I had gotten all of them by just looking at the patch and noting
which lines shouldn't have needed modifications but I obviously missed some,
especially on the lines that I was modifying anyway.  Do you have a more 
foolproof method?

One way is to have your editor show them. I have this in my .vimrc
(the characters I picked may or may not work well for your locale):
set list
set listchars=tab:»·,trail:·

Works for me.

Domen posted that one on kj (bonus detects also spaces instead of tabs):
egrep -n "^\+(.* $|        )"

in vim you may want to :set list for viewing those spaces
and afterwards :set nolist.

another possibility is to use the patch-scripts from Andrew Morton,
they warn you when trailing space is introduced.
that's the place, where i see most of them ;)

Every time that I apply a patch (similar to what max suggested),
I have a script that does 'patch --dry-run' and also greps for
trailing spaces.

This is my 'dryrun' script:

#! /bin/sh
patch -sp1 --dry-run -i $1 $2 $3 $4 $5 $6 $7 $8 $9
echo "===== trailing spaces? ====="
grep -n "^+.* $" $1 | more

What are all these arguments meant for? Why not $@?

> echo "===== trailing spaces? ====="
> grep -n "^+.* $" $1 | more

How about
grep -n '^+.*[[:space:]]$'
instead? Catches trailing tabs as well. And yes, there are plenty of those
in the kernel.

I notice whitespace problems when I review the code anyway, but script
users should also try and catch these:

  	f();
should really be
	f();

as matthew wilcox suggested rip out that unused "not-really PnP Wakeup"

your patch doesn't anymore apply to 2.6.8,
please resend it!
