Subject: [PATCH] netfilter: nf_{log,queue}: fix compilation without CONFIG_PROC_FS
This patch fixes the following compilation error:
net/netfilter/nf_log.c:373:38: error: 'struct netns_nf' has no member named 'proc_netfilter'
if procfs is not set.
The netns support for nf_log, nfnetlink_log and nfnetlink_queue_core
requires CONFIG_PROC_FS in the removal path of their respective
/proc interface since net->nf.proc_netfilter is undefined in that
case.
