-Subject: [PATCH] block/backup: move bcs bitmap initialization to job creation
-
-For backing up the state of multiple disks from the same time, a job
-for each disk has to be created. It's convenient if the jobs don't
-have to be started at the same time and if operation of the VM can be
-resumed after job creation. This would lead to a window between job
-creation and running the job, where writes can happen. But no writes
-should happen between setting up the copy-before-write filter and
-setting up the block copy state bitmap, because then new writes would
-just pass through.
-
-Commit 06e0a9c16405c0a4c1eca33cf286cc04c42066a2 moved initalization of
-the bitmap to setting up the copy-before-write filter when sync_mode
-is not MIRROR_SYNC_MODE_BITMAP. Ensure that the bitmap is initialized
-upon job creation for the remaining case too, by moving the
-backup_init_bcs_bitmap call to backup_job_create.
