From 0042fd3663662c848aaff5c65b6880e545d94b18 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 13 Apr 2017 18:38:28 +0200 Subject: migration: Call blk_resume_after_migration() for postcopy Commit d35ff5e6 ('block: Ignore guest dev permissions during incoming migration') added blk_resume_after_migration() to the precopy migration path, but neglected to add it to the duplicated code that is used for postcopy migration. This means that the guest device doesn't request the necessary permissions, which ultimately led to failing assertions. Add the missing blk_resume_after_migration() to the postcopy path.
