On Fedora release 31 (Thirty One) I have the production version
("kernel/drivers/acpi/nfit/nfit.ko.xz") in the dependency chain:
$ cat /lib/modules/5.6.0-rc1-13504-g7b27a8622f80/modules.dep | grep nfit_test.ko
extra/test/nfit_test.ko.xz: extra/test/nfit_test_iomap.ko.xz
kernel/drivers/acpi/nfit/nfit.ko.xz kernel/drivers/nvdimm/libnvdimm.ko.xz
kernel/security/keys/encrypted-keys/encrypted-keys.ko.xz
kernel/security/keys/trusted-keys/trusted.ko.xz
kernel/drivers/char/tpm/tpm.ko.xz kernel/drivers/char/hw_random/rng-core.ko.xz
I do not want to use Fedora rawhide, because AFAIK ndctl does not compile on it.
All I need now is to know the distro & kernel the 'nfit_test' module works well
with.
Do you know them?
