Subject: netfilter: Pass priv instead of nf_hook_ops to netfilter hooks
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=06198b34a3e09e06d9aecaa3727e0d37206cea77;p=linux-beck.git

netfilter: Pass priv instead of nf_hook_ops to netfilter hooks

Only pass the void *priv parameter out of the nf_hook_ops.  That is
all any of the functions are interested now, and by limiting what is
passed it becomes simpler to change implementation details.
