Subject: Re: [PATCH bpf-next v2 2/2] selftests: xsk: Add test UNALIGNED_INV_DESC_4K1_FRAME_SIZE

Sorry I forgot to update the commit message with the new commit label.
If accepted, please change the second paragraph to :

This test used to fail without the previous commit ("xsk: Fix unaligned
descriptor validation").
