Subject: [PATCH 12/12] netfilter: xt_hashlimit: use s->file instead of s->private
Date: Tue, 11 Sep 2018 02:20:44 +0200	[thread overview]
Message-ID: <20180911002044.9100-13-pablo@netfilter.org> (raw)
In-Reply-To: <20180911002044.9100-1-pablo@netfilter.org>

From: Cong Wang <xiyou.wangcong@gmail.com>

After switching to the new procfs API, it is supposed to
retrieve the private pointer from PDE_DATA(file_inode(s->file)),
s->private is no longer referred.

Fixes: 1cd671827290 ("netfilter/x_tables: switch to proc_create_seq_private")
