Thanks for reporting this. It appears to me you hit a bug that was
recently discovered: when building with `make M=some/subdirectory`,
modpost is misbehaving. Can you try whether this patch series solves
your problems:
https://lore.kernel.org/lkml/20191003075826.7478-1-yamada.masahiro@socionext.com/
In particular patch 2/6 out of the series.
Cheers,
Matthias

Right.
Since 2/6 depends on 1/6,
applying only the second one does not work.

Applying both 1 and 2 I get the following error doing make (although
it makes it a long way into the build)

Hmm, I do not see those error.
I was able to build the kernel successfully.
(I asked the 0-day bot to test whole of my patch set
in case I am missing something.)
Could you share the steps to reproduce the errors and your .config file?

Sorry, I do not understand why you are doing this.

You need to clarify your problem.
In the first post from you, you pointed out
"hundreds of new warnings introduced by namespaces in 5.4-rc1 when
building my module"
So, 1/6 and 2/6 should address that problem.
https://lore.kernel.org/patchwork/patch/1133628/
https://lore.kernel.org/patchwork/patch/1133626/
Then, in the previous email ("Applying both 1 and 2 I get the
following error doing make")
it looks like you were talking about in-kernel building
instead of the external module.
Then, in this email, you are talking about "make nsdeps".
"make nsdeps" obviously does not support M=.
I am afraid you are mixing up different issues,
which is so confusing. (and I am afraid you were too confused)
Currently, the namespace is used only by USB_STORAGE.
So, it should not be a problem for your module.
To sum up, you do not need to run nsdeps at all.
The hundreds of false-positive warnings came from the modpost bug,
and should be fixed soon.

ok - so to sum up, it sounds like you are saying the 350 false
positives (see attached file) that happen on building cifs.ko .will be
fixed by a
future change to modpost? This is a typical module build ...
download and install current kernel package (in this case Ubuntu
5.4-rc1). which saves huge amount of build time, then build just the
module of interest (in my case cifs.ko)
cd fs/cifs
make C=1 -C /usr/src/linux-headers-`uname -r` M=`pwd` modules
If nsdeps is not needed to fixup some namespace issue then shouldn't
be a problem, just trying to avoid the distraction of 300+
warning messages every time I build just this one module. Is there a
workaround?

Yes, the reason for you to see these false positive warnings is a bug in
modpost. The patch series we were referring to addresses this problem
(and some others). I do not believe you need to run nsdeps to fixup
anything in fs/cifs at this time.

Sorry for the noise this creates. The only known workaround is to
locally apply the complete patch series.
