If "y" is not a valid option, we'll need to adjust 0-day's dependency specification for ndctl test:
wfg /c/lkp-tests% cat include/ndctl need_kconfig: - CONFIG_HAVE_DMA_CONTIGUOUS=y - CONFIG_CMA=y - CONFIG_DMA_CMA=y - CONFIG_CMA_SIZE_MBYTES=200 - CONFIG_LIBNVDIMM - CONFIG_BLK_DEV_PMEM - CONFIG_ND_BLK - CONFIG_BTT=y - CONFIG_NVDIMM_PFN=y - CONFIG_NVDIMM_DAX=y - CONFIG_ZONE_DEVICE=y
In the above list, a bare "CONFIG_BLK_DEV_PMEM" means "y" or "m" are both acceptable.
