* Dynamic label support: To date namespace label support has been
limited to disambiguating cases where PMEM (direct load/store) and BLK
(mmio aperture) accessed-capacity alias on the same DIMM. Since 4.9 added
support for multiple namespaces per PMEM-region there is value to
support namespace labels even in the non-aliasing case. The presence of
a valid namespace index block force-enables label support when the
kernel would otherwise rely on region boundaries, and permits the region
to be sub-divided.
* Handle media errors in namespace metadata: Complement the error
handling for media errors in namespace data areas with support for
clearing errors on writes, and downgrading potential machine-check
exceptions to simple i/o errors on read.
* Device-DAX region attributes: Add 'align', 'id', and 'size' as
attributes for device-dax regions. In particular this enables userspace
tooling to generically size memory mapping and i/o operations. Prevent
userspace from growing assumptions / dependencies about the parent
device topology for a dax region. A libnvdimm namespace may not always
be the parent device of a dax region.
* Various cleanups and small fixes.

Merge tag 'libnvdimm-for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The libnvdimm pull request is relatively small this time around due to
some development topics being deferred to 4.11.
As for this pull request the bulk of it has been in -next for several
releases leading to one late fix being added (commit 868f036fee
("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It
has received a build success notification from the 0day-kbuild robot
and passes the latest libnvdimm unit tests.
Summary:
- Dynamic label support: To date namespace label support has been
limited to disambiguating cases where PMEM (direct load/store) and
BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since
4.9 added support for multiple namespaces per PMEM-region there is
value to support namespace labels even in the non-aliasing case.
The presence of a valid namespace index block force-enables label
support when the kernel would otherwise rely on region boundaries,
and permits the region to be sub-divided.
- Handle media errors in namespace metadata: Complement the error
handling for media errors in namespace data areas with support for
clearing errors on writes, and downgrading potential machine-check
exceptions to simple i/o errors on read.
- Device-DAX region attributes: Add 'align', 'id', and 'size' as
attributes for device-dax regions. In particular this enables
userspace tooling to generically size memory mapping and i/o
operations. Prevent userspace from growing assumptions /
dependencies about the parent device topology for a dax region. A
libnvdimm namespace may not always be the parent device of a dax
region.
- Various cleanups and small fixes"
