Subject: [PATCH bpf v2 2/3] samples: bpf: add missing munmap in xdpsock
Date: Wed,  3 Mar 2021 19:56:35 +0100	[thread overview]
Message-ID: <20210303185636.18070-3-maciej.fijalkowski@intel.com> (raw)
In-Reply-To: <20210303185636.18070-1-maciej.fijalkowski@intel.com>

We mmap the umem region, but we never munmap it.
Add the missing call at the end of the cleanup.
