From e6ce5e92248be5547daaee3eb6cd226e9820cf7b Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Mon, 27 Jul 2020 22:42:22 +0300 Subject: migration/block-dirty-bitmap: fix dirty_bitmap_mig_before_vm_start Using the _locked version of bdrv_enable_dirty_bitmap to bypass locking is wrong as we do not already own the mutex. Moreover, the adjacent call to bdrv_dirty_bitmap_enable_successor grabs the mutex.
