From bc9fcbf9cb8ec76d340da16fbf48a9a316e14c52 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 19 Oct 2011 14:31:18 +0200 Subject: block: move blk_throtl prototypes to block/blk.h blk_throtl interface is block internal and there's no reason to have them in linux/blkdev.h. Move them to block/blk.h. This patch doesn't introduce any functional change.
