You need this one as well, like I told Greg the other day:

    genhd: fix leftover might_sleep() in blk_free_devt()

    Commit 2da78092 changed the locking from a mutex to a spinlock,
    so we now longer sleep in this context. But there was a leftover
    might_sleep() in there, which now triggers since we do the final
    free from an RCU callback. Get rid of it.
