Subject: [PATCH] LightNVM fix for 4.9-rc5

Hi Jens,

A small calculation bug sneaked into 4.9, which led to data loss using the rrpc
FTL.

Can the fix be picked up for next -rc, or should I mark it for stable after the
4.9 release?

We can put it in this release, it's a regression fix for a bug
introduced in this cycle. I'll add it.
