Subject: [PATCH] impr: Fix ptrdiff_t print formatting
Date: Tue, 30 Jan 2018 09:48:02 +0000	[thread overview]
Message-ID: <20180130094802.30147-1-jhogan@kernel.org> (raw)

ipmr_vif_seq_show() prints the difference between two pointers with the
format string %2zd (z for size_t), however the correct format string is
%2td instead (t for ptrdiff_t).

The same bug in ip6mr_vif_seq_show() was already fixed long ago by
commit d430a227d272 ("bogus format in ip6mr").
