[Devel] [PATCH 8/8] Forget the zero_it argument of sk_alloc()
Pavel Emelyanov
xemul at openvz.org
Wed Oct 31 06:59:16 PDT 2007
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.
