Subject: [dpdk-stable] [dpdk-dev] [PATCH] vfio: fix mem leak when unmapping resource
Date: Sun, 14 Jun 2020 21:59:59 +0800 [thread overview]
Message-ID: <20200614140036.1D4AF4C90@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")
