From 8b7f6fbbdc5545f749864fdf295f2fae14c7ef0a Mon Sep 17 00:00:00 2001 From: Luiz Capitulino Date: Thu, 26 Jul 2012 20:41:53 -0300 Subject: [PATCH] hmp: hmp_cont(): don't rely on QERR_DEVICE_ENCRYPTED This commit changes hmp_cont() to loop through all block devices and proactively set an encryption key for any encrypted device missing a key. This change is needed because QERR_DEVICE_ENCRYPTED is going to be dropped by a future commit.
