Add "UBIFS: fix a horrid bug" to 3.2 branch?

[Christoph Fritz]

Hi Ben,

 I can't find an incarnation of commit "UBIFS: fix a horrid
bug" (605c912) in current stable branch 3.2 but 3.0, 3.4, 3.9 and
current.

Are there any concerns adding these commits:

    UBIFS: prepare to fix a horrid bug
    UBIFS: fix a horrid bug

Thanks
 -- Christoph
