From: Jens Axboe <ax...@fb.com>
3.4.105-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit 46f341ffcfb5d8530f7d1e60f3be06cce6661b62 upstream.
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.
