Subject: [PATCH 1/2] Create: check for UnSet when looking at chunk
Cc: linux-raid [at] vger.kernel.org, Williams, Dan J <dan.j.williams [at] intel.com>, Ciechanowski, Ed <ed.ciechanowski [at] intel.com>
A default chunk size of 0 gets modified to UnSet, so any location that
checks for !chunk really needs to check for !(chunk || chunk == UnSet).
