My apologies for the confusion. The cover letter is indeed misleading
w.r.t. the dma-buf patch.  It isn't a bugfix, so it shouldn't hit -rc.

Since without this patch compiling the seqcount series will fail, it
will be best to merge it through tip instead.

So all I need for now is a reviewed-by tag :) I will forwoard it to the
tip tree afterwards.

Thanks,
