Subject: [NET]: Make the sk_clone() lighter
X-Git-Tag: v2.6.24-rc2~56^2~9
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8fd1d178a3f177777707ee782f12d93e9a7eb5e5;p=linux-2.6

[NET]: Make the sk_clone() lighter

The sk_prot_alloc() already performs all the stuff needed by the
sk_clone(). Besides, the sk_prot_alloc() requires almost twice
less arguments than the sk_alloc() does, so call the sk_prot_alloc()
saving the stack a bit.
