Right, But i don't think that they are necessary.
after bdrv_is_allocated_co_entry has basically completed all main
task, it call qemu_coroutin

Since this main process will stop within qemu_coroutine_enter() until
bdrv_is_allocated_co_entry() is completed, three lines of condition

This patch adds the .bdrv_co_is_allocated() interface which is identical
to .bdrv_is_allocated() but runs in coroutine context. Running in
coroutine context implies that other coroutines might be performing I/O
at the same time. Therefore it must be safe to run while the following
