From: Michael Holzheu Date: Thu, 15 Jan 2015 09:21:20 +0000 (+0100) Subject: s390/bpf: Fix offset parameter for skb_copy_bits() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d86eb7448e6de97b1319ea935f77b65590dbc049;p=linux-beck.git s390/bpf: Fix offset parameter for skb_copy_bits() Currently the offset parameter for skb_copy_bits is changed in sk_load_word() and sk_load_half(). Therefore it is not correct when calling skb_copy_bits(). Fix this and use the original offset for the function call.
