Andrew,
As discussed in the '[PATCH] kernel/module.c has something to hide.
(whitespace cleanup)' thread, I've started doing whitespace cleanups to
make the kernel adhere closer to Documentation/CodingStyle.
As per your request I'm doing releatively few large patches against latest
Linus kernel and sending them to you as I generate them instead of
batching them up. You also asked me to try and keep the most key people
in the loop, so I've added what I think are a few central people regarding
the code I've changed to CC, as well as the people who commented on the
previous thread. I hope that hits the mark.
I started with the if/else cleanups.
Judging by if statements only we can see that this patch does aproximately
one seventh of the work :
before this patch:
juhl@dragon:~/download/kernel/linux-2.6.12-rc4-orig$ find ./ -name *.[ch] -exec egrep -r -H "if *\(.+\).*;.*" '{}' \; | awk -F: {'print $1'} | sort | uniq | wc -l
1403
after this patch:
juhl@dragon:~/download/kernel/linux-2.6.12-rc4$ find ./ -name *.[ch] -exec egrep -r -H "if *\(.+\).*;.*" '{}' \; | awk -F: {'print $1'} | sort | uniq | wc -l
1288
It changes code such as this
if (foo) something();
else something_else()
a_third_thing();
into
if (foo)
something();
else
something_else();
a_third_thing();
The patch covers the following dirs :
Documentation/
crypto/
fs/
init/
kernel/
lib/
scripts/
usr/
There are no functional changes made by this patch, whitespace changes
only. To ensure this
I opted to do only one type of cleanup and then when that is done create
incremental patches with the other cleanups instead of doing all cleanups
(if/else, tabs vs spaces, trailing whitespace, spaces between function
name and opening parenthesis, etc) to a single file at once. Do you agree
with this approach or would you rather see each file cleaned up completely
in one go?
I chose this approach to make the individual patches easier to review for
correctness.
Since this patch is pretty huge (~192K), but within your specified
100-400K range, I've put it online at this address :
http://ragnarok.dif.dk/~juhl/kernel_patches/if-else-cleanup-1.patch
but I can of course send it inline or attached in whatever form if wanted
to anyone who asks.
To ensure that the patch really only makes whitespace cleanups I've read
through the diff file 3 times and I've compile tested a 2.6.12-rc4 kernel
with the patch applied (and didn't see any breakage). I have not yet done
any md5sum or size comparison of the object files created.
Another thing; Bodo Eggert made a nice patch that cleaned up trailing
whitespace. I did not do my patch on top of his, but if that is wanted
I'll redo the patch and base any future patches on top of his. Would that
be good? Personally I think it would, but I'd like your oppinion :)
Patch is of course
