Jiri's reply:

"This patch just removes pointless try_to_freeze(), that's guaranteed
not to do anything and return immediately, as the btrfs kthread is not
freezable.  So I don't think it's needed in stable; the semantics is
equivalent before and after."

Sasha was fine with dropping the patch from stable candidates and this
has not changed. Thanks.

Indeed, I thought I dropped it but I see that I didn't. My bad, sorry.
