You always could.

You did and you didn't.  For instance, in patch 1/3, the new
cgroup_rdma.c file has a notice of GPLv2, but no notice of copyright, so
it's incomplete.  You need to put a copyright notice in the file too.
And in the file cgroup_rdma.h you have neither a copyright notice or a
license statement.  It's a plain file.

In patch 2/3, the file infiniband/core/cgroup.c has a copied dual
license (not necessary, it can be GPL only), but again, it is missing
the copyright notice.

You need to finish the conversation you and Christoph were having in
that thread, but you also need a v11 of the patchset that fixes the
copyright issues.

Yes.
