[PATCH 0/8] nfit, libnvdimm: async address range scrub

Given the capacities of next generation persistent memory devices a scrub operation to find all poison may take 10s of seconds. We want this scrub work to be done asynchronously with the rest of system initialization, so we move it out of line from the NFIT probing, i.e. acpi_nfit_add(). However,

[PATCH 1/8] libnvdimm, nfit: centralize command status translation

The return value from an 'ndctl_fn' reports the command execution status, i.e. was the command properly formatted and was it successfully submitted to the bus provider. The new 'cmd_rc' parameter allows the bus provider to communicate command specific results, translated into common error codes.

[PATCH 7/8] nfit: disable userspace initiated ars during scrub

[PATCH 6/8] nfit: scrub and register regions in a workqueue

[PATCH 4/8] nfit, tools/testing/nvdimm: unify common init for acpi_nfit_desc

The nvdimm unit test infrastructure performs its own initialization of an acpi_nfit_desc to specify test overrides over the native implementation. Make it clear which attributes and operations it is overriding by re-using acpi_nfit_init_desc() as a common starting point. Signed-off-by: Dan Willia
