Remove this empty _post method ?

This revision is now accepted and ready to land.Aug 27 2019, 3:53 PM

As expected several ports failed, unfortunately some of them have rather nasty code which will require a lot of care and testing.

most notably open-vm-tools has copy-pasted and modified old variant of null_unlock. Thus removal of the flags argument will wait a little bit until I get around to sorting this out.

Can you post the coccinelle script used somewhere? Thanks.
