[PATCH 04/10] Remove migrate_set_block_enabled in checkpoint |
Date: |
Wed, 13 Jan 2021 10:46:29 +0800 |
From: "Rao, Lei" <lei.rao@intel.com>
We can detect disk migration in migrate_prepare, if disk migration
is enabled in COLO mode, we can directly report an error.and there
is no need to disable block migration at every checkpoint.
