[Qemu-devel] [PATCH v2 0/4] nvdimm: fixes for (non-)dax backends

[Haozhong Zhang <haozhong.zhang@intel.com>]

This is v2 of patch series
https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05919.html.

Changes in v2:
* Patch 2: use major/minor numbers of device and sysfs to check
  whether a backend file refers to DAX device. (Dan & Stefan)

* Patch 3: set ACPI_NFIT_MEM_NOT_ARMED bit of state flags in guest
  NVDIMM region mapping structure. This behavior is controlled by a
  new QEMU nvdimm option "restrict". See details in patch 3. (Dan)

* Patch 4: drop the "align" property and get the alignment of DAX
  device by QEMU itself.

* Wrap Linux specific code by __linux__. (Stefan)


Haozhong Zhang (4):
  nvdimm: add a macro for property "label-size"
  nvdimm: warn if the backend is not a DAX device
  nvdimm: add a boolean option "restrict"
  util/mmap-alloc: account for DAX device in qemu_fd_getpagesize
