[PATCH 1/1] nvdimm: use the right length of "pmem"
From: Nicolas Iooss
Date: Sat Oct 29 2016 - 07:29:38 EST
In order to test that the name of a resource begins with "pmem", call
strncmp() with 4 as length instead of 3 to match the whole prefix.
Fixes: 16660eaea0cc ("libnvdimm, namespace: update label implementation
for multi-pmem")
