From 55aff7f133b0eb20b2c8a2a3e1307240aab8044c Mon Sep 17 00:00:00 2001 From: Jeff Cody Date: Mon, 27 Jan 2014 16:09:12 -0500 Subject: [PATCH] block: remove QED .bdrv_make_empty implementation The QED .bdrv_make_empty() implementation does nothing but return -ENOTSUP, which causes problems in bdrv_commit(). Since the function stub exists for QED, it is called, which then always returns an error. The proper way to not support an optional driver function stub is to just not implement it, so let's remove the stub.
