I would not say that.
I just want to put as much code as possible into the test-coverage.

If there is a good reason to opt out of the header-test, that is OK.
We should take a look at the cause of the error
before blindly adding it into the blacklist.


For this particular case, I just thought some functions
could be localized in net/netfilter/, and would be cleaner.

Having said that, I am not familiar enough with
the netfilter subsystem.
So, this should be reviewed by the experts in the area.


Anyway, CONFIG_NF_TABLES seems mandatory to compile
include/net/netfilter/nf_tables_*.h

So, I will queue the following patch
to suppress the error for now.

diff --git a/include/Kbuild b/include/Kbuild

This test just landed in upstream,
and will take some time to iron out the issues.

If I am disturbing people too much,
I perhaps need to loosen the policy.
Sorry if this test is too annoying.


Thanks.
