Question about ndctl unit tests

Question about ndctl unit tests

[Qi, Fuli]

Hi,

When I ran the unit tests, I found "libndctl" and "dsm-fail" cannot pass the test.
Here is the test log.

# less test/libndctl.log

  "sector_size":512,
  "blockdev":"pmem1.1"
}
FAIL dsm-fail (exit status: 250)

And my kernel version:
$ uname -a
Linux 4.18.0-rc2+ #25 SMP

I guess the reason is that the nfit_test module cannot be removed.
# modprobe -r nfit_test
modprobe: FATAL: Module nfit_test is in use.
# lsmod | grep nfit_test
nfit_test              40960  8
nd_pmem                20480  1 nfit_test
nfit                   65536  1 nfit_test
device_dax             20480  2 dax_pmem,nfit_test
libnvdimm             163840  7 dax_pmem,nfit_test,nd_btt,nd_pmem,nd_e820,nd_blk,nfit
nfit_test_iomap        20480  6 dax_pmem,nfit_test,device_dax,nd_pmem,libnvdimm,nfit

Does anyone know how to fix it?

Thank you very much.

Yes, sorry, we recently reworked some tests. Grab our work-in-progress
kernel branch here:

    git://git.kernel.org/pub/scm/linux/kernel/git/djbw/nvdimm.git
libnvdimm-pending

This will move to nvdimm/nvdimm.git libnvdimm-for-next in the coming
weeks for 4.19.

You'll also want to grab:

    https://patchwork.kernel.org/patch/10495297/

...for the error handling tests. This will appear on
github.com/pmem/ndctl master soon.

OK, I see.
Thank you very much.
