Sounds good. The config_check.c file itself lists the dependencies:
void check(void) { /* * These kconfig symbols must be set to "m" for nfit_test to * load and operate. */ BUILD_BUG_ON(!IS_MODULE(CONFIG_LIBNVDIMM)); BUILD_BUG_ON(!IS_MODULE(CONFIG_BLK_DEV_PMEM)); BUILD_BUG_ON(!IS_MODULE(CONFIG_ND_BTT)); BUILD_BUG_ON(!IS_MODULE(CONFIG_ND_PFN)); BUILD_BUG_ON(!IS_MODULE(CONFIG_ND_BLK)); BUILD_BUG_ON(!IS_MODULE(CONFIG_ACPI_NFIT)); BUILD_BUG_ON(!IS_MODULE(CONFIG_DEV_DAX)); BUILD_BUG_ON(!IS_MODULE(CONFIG_DEV_DAX_PMEM)); }
