Subject: [dpdk-dev]  [PATCH v2] vfio: fix mem leak when unmapping resource
Date: Fri, 11 Sep 2020 18:57:42 +0800
Message-ID: <1599821862-27816-1-git-send-email-wangyunjian@huawei.com> (raw)
In-Reply-To: <20200614140034.E5CDC49E0@dpdk.org>

From: Yunjian Wang <wangyunjian@huawei.com>

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
