If the earlier kfunc filter patch 
(https://lore.kernel.org/bpf/1ECC8AAA-C2E6-4F8A-B7D3-5E90BDEE7C48@isovalent.com/) 
looks fine to you, please include it into the next revision. This patchset needs 
it. Usual thing to do is to keep my sob (and author if not much has changed) and 
add your sob. The test needs to be broken out into a separate patch though. It 
needs to use the '__failure __msg("calling kernel function bpf_sock_destroy is 
not allowed")'. There are many examples in selftests, eg. the dynptr_fail.c.

Please also fix the subject in the patches. They are all missing the bpf-next 
and revision tag.
