From 46f341ffcfb5d8530f7d1e60f3be06cce6661b62 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 16 Sep 2014 13:38:51 -0600 Subject: 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.
