If anyone has any objections, please let me know. You need this one as well, like I told Greg the other day: commit 46f341ffcfb5d8530f7d1e60f3be06cce6661b62 Author: Jens Axboe Date: Tue Sep 16 13:38:51 2014 -0600 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. Reported-by: Pontus Fuchs Signed-off-by: Jens Axboe -- Jens Axboe
