[PATCH 0/2] Init vNVDIMM LSA if applicable

[Robert Hoo]

QEMU option "-device nvdimm,...,label-size=" designates a vNVDIMM with
Label Storage Area (LSA), where stores the namespace labels and conforms to
some format and rules defined by NVDIMM label protocol[1].

Recent guest Kernel, will by validating LSA to determine if the NVDIMM is
label-capable. So without initialization, guest Kernel will judge it
label-less, though it actually support label.

This patch set, is to init vNVDIMM's LSA, so that guest Kernel can
correctly identify and use it.
