Subject: [dpdk-dev] [PATCH] test/mbuf: fix virtual address conversion
Date: Mon,  5 Jul 2021 09:27:34 +0200	[thread overview]
Message-ID: <20210705072734.22484-1-olivier.matz@6wind.com> (raw)

Seen with address sanitizer.

rte_mempool_virt2iova() can only be used on mempool elements. In this case,
it is incorrect, and rte_mem_virt2iova() has to be used.

Bugzilla ID: 737
Fixes: 7b295dceea07 ("test/mbuf: add unit test cases")
Cc: stable@dpdk.org
