[PATCH v4 2/3] acpi nfit: Enable to show what feature is supported via ND_CMD_CALL for nfit_test

Re: Segmentation fault when running "make M=tools/testing/nvdimm"

Thanks for reply, Dan. After switchingfrom 4.13rc6 to 4.14rc1, this compilation time segmentation fault for libnvdimm.o no longer repros. Doc does not match the test code below does not match the kconfig requirements under the "Unit Tests" section in https://github.com/pmem/ndctl  

[PATCH v4 0/3] acpi nfit: make emulation of translate SPA on nfit_test

Hello I made a v4 patch set to emulate translate SPA by nfit_test.ko module. If possible, please merge it. This patch set is to emulate translate SPA feature by nfit_test.ko. Certainly the nfit acpi driver supports translate SPA interface via ND_CMD_CALL. But nfit_test does not support

[PATCH v5 0/2] dax, dm: stop requiring dax for device-mapper

Changes since v4: * redo a botched send of v3 * rebase on 4.14-rc1 * rewrite the changelog of patch2 to drop broken references to the "built-in portion of device-mapper" (Mike) --- Bart points out that the DAX core is unconditionally enabled if device-mapper is enabled. Add some config

[PATCH v5 2/2] dm: allow device-mapper to operate without dax support

Change device-mapper's 'select DAX' dependency to be dependent on the presence of at least one DAX_DRIVER. This allows device-mapper to be built without bringing the DAX core along which is especially wasteful when there are no DAX drivers, like BLK_DEV_PMEM, configured. Cc: Alasdair Kergon

[PATCH v5 1/2] dax: introduce CONFIG_DAX_DRIVER

In support of allowing device-mapper to compile out idle/dead code when there are no dax providers in the system, introduce the DAX_DRIVER symbol. This is selected by all leaf drivers that device-mapper might be layered on top. This allows device-mapper to conditionally 'select DAX' only when a
