Hi,
I am building and installing the linux kernel from the 'libnvdimm-for-next' branch at git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git with the 'nfit_test' kernel module.
I have set in the .config file:
CONFIG_X86_PMEM_LEGACY=m
CONFIG_ZONE_DEVICE=y
CONFIG_LIBNVDIMM=m
CONFIG_BLK_DEV_PMEM=m
CONFIG_ND_BLK=m
CONFIG_BTT=y
CONFIG_NVDIMM_PFN=y
CONFIG_NVDIMM_DAX=y
CONFIG_DEV_DAX_PMEM=m
I ran:
$ make
$ make M=tools/testing/nvdimm
$ sudo make M=tools/testing/nvdimm modules_install
$ sudo make modules_install
and I got:
[...]
DEPMOD 4.19.0-rc4-nfit_test
depmod: WARNING: /lib/modules/4.19.0-rc4-nfit_test/extra/test/nfit_test.ko.xz needs unknown symbol libnvdimm_test

Does anyone know what could be wrong here?

Do you get the error if you run the same script again? For external
modules to find symbols the symbol map needs to be installed, but the
first time you run the process nothing has been installed. So, it's
possible to see this error on the first run on a new kernel version,
but it's benign and should disappear for subsequent builds.

My script:
$ make
$ make M=tools/testing/nvdimm
The first time I run 'modules_install' I get:
