Subject: [dpdk-dev] [PATCH v4 6/7] mempool: prevent objects from being across pages
Date: Tue,  5 Nov 2019 16:37:05 +0100
Message-ID: <20191105153707.14645-7-olivier.matz@6wind.com> (raw)
In-Reply-To: <20191105153707.14645-1-olivier.matz@6wind.com>

When populating a mempool, ensure that objects are not located across
several pages, except if user did not request iova contiguous objects.
