Subject: [PATCH] mbuf: fix leak and errno on pool creation error
Date: Mon, 19 Sep 2016 14:34:41 +0200	[thread overview]
Message-ID: <1474288481-19573-1-git-send-email-olivier.matz@6wind.com> (raw)

On error, the mempool object has to be freed, and rte_errno should be a
positive value.

Fixes: 152ca517900b ("mbuf: use default mempool handler from config")
