Subject: [dpdk-dev] [PATCH v2 01/11] eal: add const in prefetch functions
Date: Thu, 25 Jun 2015 23:05:09 +0100	[thread overview]
Message-ID: <1435269919-7007-2-git-send-email-pablo.de.lara.guarch@intel.com> (raw)
In-Reply-To: <1435269919-7007-1-git-send-email-pablo.de.lara.guarch@intel.com>

rte_prefetchX functions included volatile void *p as parameter,
but the function does not modify it, so it should include the const keyword.
