I'm afraid that's not yet the case. I see you're using 3.4.0
as your base version, so it wouldn't be of much help anyway.

I took a quick peek at the git tree pointed to in the bug
report and it looks like the backport was created not through
cherry-picking of the relevant upstream commits, but by
applying the patches straight off the mailing list.

That is *not* the correct way to perform a backport, for a
number or reasons:

  * you lose metadata such as R-b tags;

  * you don't have any information linking the downstream
    commit to the respective upstream commit, which will
    make it more difficult to figure out which commits can
    be dropped during the next rebase;

  * most importantly, any issue pointed out during review
    that has a straightforward enough fix not to warrant
    a respin will *still be present* in the backport.
