Subject: [NET]: Forget the zero_it argument of sk_alloc()
X-Git-Tag: v2.6.24-rc2~56^2~7
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=6257ff2177ff02d7f260a7a501876aa41cb9a9f6;p=linux-2.6-omap-h63xx.git

[NET]: Forget the zero_it argument of sk_alloc()

Finally, the zero_it argument can be completely removed from
the callers and from the function prototype.

Besides, fix the checkpatch.pl warnings about using the
assignments inside if-s.

This patch is rather big, and it is a part of the previous one.
I splitted it wishing to make the patches more readable. Hope
this particular split helped.
