Paolo Bonzini 6b98bd6495 block: plug whole tree at once, introduce bdrv_io_unplugged_begin/end ... Extract the handling of io_plug "depth" from linux-aio.c and let the main bdrv_drain loop do nothing but wait on I/O. Like the two newly introduced functions, bdrv_io_plug and bdrv_io_unplug now operate on all children. The visit order is now symmetrical between plug and unplug, making it possible for formats to implement plug/unplug.
