A toolchain update in Fedora 32 caused new compile errors due to
multiple definitions of dimm_ops structures. The declarations in
'private.h' for the various NFIT families are present so that libndctl

A follow-up to the region-align kernel enabling, [1], update ndctl to
enumerate region alignment, and update the unit tests to account for the
kernel's default compatible alignment.
Given that changing the default is a surefire way to create incompatible
namespaces I do not think it makes sense
With the new kernel updates to enforce wider alignment constraints by
default, it is increasingly important to report why provisioning failed.
Move some debug messages to error messages when they indicate a hard
failure, and drop the generic message when something more precise has
been emitted.
Add support for the new kernel facility to set space alignment
constraints at the region level. Update the unit tests to bypass the
default 16MiB alignment constraint. Add the new parameter to the default
region listing given how central it is to understanding the valid values

The NDD_ALIASING flag is used to indicate where pmem capacity might
alias with blk capacity and require labeling. It is also used to
indicate whether the DIMM supports labeling. Separate this latter
capability into its own flag so that the NDD_ALIASING flag is scoped to
true aliased
The align attribute applies an alignment constraint for namespace
creation in a region. Whereas the 'align' attribute of a namespace
applied alignment padding via an info block, the 'align' attribute
applies alignment constraints to the free space allocation.
The default for 'align' is the

Aneesh reports that PowerPC requires 16MiB alignment for the address
range passed to devm_memremap_pages(), and Jeff reports that it is
possible to create a misaligned namespace which blocks future namespace
creation in that region. Both of these issues require namespace
alignment to be managed at

A toolchain update in Fedora 32 caused new compile errors due to
