Subject: net: add kmemcheck annotation in __alloc_skb()
X-Git-Tag: v2.6.38-rc4~15^2~48
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c2aa3665cf8510b1665ee2f5a9525cf7be6dec4f;p=pandora-kernel.git

net: add kmemcheck annotation in __alloc_skb()

pskb_expand_head() triggers a kmemcheck warning when copy of
skb_shared_info is done in pskb_expand_head()

This is because destructor_arg field is not necessarily initialized at
this point. Add kmemcheck_annotate_variable() call in __alloc_skb() to
instruct kmemcheck this is a normal situation.
