Subject: [PATCH] samples/seccomp: fix 32-bit build
Date: Mon, 7 Jan 2019 16:16:31 -0700 [thread overview]
Message-ID: <20190107231631.1849-1-tycho@tycho.ws> (raw)
Both the .o and the actual executable need to be built with -m32 in order
to link correctly.
Signed-off-by: Tycho Andersen <tycho@tycho.ws>
Reported-by: Ingo Molnar <mingo@kernel.org>
Fixes: fec7b6690541 ("samples: add an example of seccomp user trap")

I guess x86 can pick this up directly? Not sure where it should go
exactly.
