From a7928c1578c550bd6f4dec62d65132e6db226c57 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 17 Apr 2015 22:37:20 +0200 Subject: block: move PM request support to IDE This removes the request types and hacks from the block code and into the old IDE driver. There is a small amunt of code duplication due to this, but it's not too bad.
