Subject: [PATCH v16 05/23] selftests/vm: Make gcc check arguments of sigsafe_printf()
Date: Fri, 17 Jan 2020 18:19:44 +0530	[thread overview]
Message-ID: <d2721f0dcc5f67a9ca989995611427a8abe4747d.1579265066.git.sandipan@linux.ibm.com> (raw)

In-Reply-To: <cover.1579265066.git.sandipan@linux.ibm.com>

From: Thiago Jung Bauermann <bauerman@linux.ibm.com>

This will help us ensure we print pkey_reg_t values correctly in
different architectures.
