Subject: [dpdk-dev]  [PATCH] vfio: fix mem leak when unmapping resource
Date: Sun, 14 Jun 2020 21:59:59 +0800
Message-ID: <20200614140034.E5CDC49E0@dpdk.org> (raw)

The 'vfio_res' is not freed when unmapping resource by primary process.
This leads to memory leak.

Fixes: ab53203e194b ("vfio: enable unmapping resource for secondary")
Cc: stable@dpdk.org
