Subject: [dpdk-dev] [PATCH v2 12/24] rte_mbuf.h: explicit casts for int16 to uint16
Date: Fri, 11 May 2018 09:59:54 +0800	[thread overview]
Message-ID: <152600399485.54839.8252106635185769195.stgit@localhost.localdomain> (raw)
In-Reply-To: <152600382101.54839.18392182958431211001.stgit@localhost.localdomain>

differences to the atomic16 are signed, but the
atomic16 itself is unsigned.  It needs to be
made explicit with casts.
