Khaled, could you build a test kernel 4.15.0-60-generic with fix please?

Title:
[SRU] Unable to modify/create-namespace over
Tested latest ndctl version 66 with ubuntu 4.15.0-60-generic
Still the same issue. Do I need a kernel fix?

Seeing this on bionic with 4.15.0-60-generic x86_64 kernel.
Any movement on this issue?

Sujith,
What is the other issue and have you identified the other patches
required to completely get the namespace modification functionality
working?

This is a kernel issue and we have seen this with upstream kernels and verified
the fixes on upstream kernels.
I expect bionic kernel 4.15 and above kernels to display this defect.
Although I have not tried applying only the kernel fix on bionic, the test
kernel shared above shows that original
Has this been tested with Disco (19.04) or Cosmic (18.10)? IOW does
this issue with ndctl only exist in Bionic, or does it carry forward?

This bug was erroneously marked for verification in bionic; verification
is not required and verification-needed-bionic is being removed.

Another issue pops-up, looks like there are a few nvdimm patches that
require backporting:
# ndctl create-namespace -e "namespace0.0" -m fsdax -f -vvv
libndctl: sizeof_namespace_index: nmem0: label area (1024) too small to host
(256 byte) labels
libndctl: sizeof_namespace_index: nmem0: label
I have built a bionic test kernel with those fixes (+2 others needed for
backporting) for testing.
The kernel can be found at:
https://kernel.ubuntu.com/~kmously/1811660/kernel-kmously-96d0cc8-l7Et/
@Sujith Pandel can you please confirm of this kernel fixes the problem
or not?
Thanks.
