Subject: [NETLINK]: Remove unused dst_pid field in netlink_skb_parms
X-Git-Tag: v2.6.20-rc2~6^2~13^2~147
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=4e9b82693542003b028c8494e9e3c49615b91ce7;p=linux-2.6-omap-h63xx.git

[NETLINK]: Remove unused dst_pid field in netlink_skb_parms

The destination PID is passed directly to netlink_unicast()
respectively netlink_multicast().
