Subject: [PATCH blktests 1/4] common/multipath-over-rdma: Fix expand_ipv6_addr()
Date: Fri, 15 Nov 2019 09:07:08 -0800 [thread overview]
Message-ID: <20191115170711.232741-2-bvanassche@acm.org> (raw)
In-Reply-To: <20191115170711.232741-1-bvanassche@acm.org>
For IPv6 address ::1, instead of returning
0:0000:0000:0000:0000:0000:0000:0000:0001, return
0000:0000:0000:0000:0000:0000:0000:0001.
