Subject: [PATCH 012/217] Expose ndctl_bus_nfit_translate_spa as a public
|
|
|
2eb93d |
function.
|
|
|
2eb93d |
|
|
|
2eb93d |
The motivation is to allow access to ACPI defined NVDIMM Root Device
|
|
|
2eb93d |
_DSM Function Index 5(Translate SPA). The rest of the _DSM functions,
|
|
|
2eb93d |
which are mostly ARS related, are already public.
|
|
|
2eb93d |
|
|
|
2eb93d |
Basically move ndctl_bus_nfit_translate_spa declaration from private.h
|
|
|
2eb93d |
to libndctl.h.
