[Qemu-devel] [question] savevm/delvm: Is it neccesary to perform bdrv_drain_all before savevm and delvm?

Hi, I noticed that bdrv_drain_all is performed in load_vmstate before bdrv_snapshot_goto, and bdrv_drain_all is performed in qmp_transaction before internal_snapshot_prepare, so is it also neccesary to perform bdrv_drain_all in savevm and delvm? Thanks, Zhang Haoyu
