Subject: [dpdk-stable] [PATCH] mem: fix incorrect munmap in error unwind
Date: Mon,  6 Jan 2020 12:55:53 -0800
Message-ID: <20200106205553.3696-1-stephen@networkplumber.org> (raw)

The loop to unwind existing mmaps was only unmapping the
first segment.

Also, remove obvious redundant assignment.

Fixes: 66cc45e293ed ("mem: replace memseg with memseg lists")
