Frederick Mayle c14d6885eb devices: virtio: block: fix kick event handling when using io_uring 
There is a probably a more elegant solution where `EventAsync` provides
a `futures::stream::Stream` interface, then, instead of using
`FuturesUnordered`, we call `StreamExt::for_each_concurrent` to perform
the `process_one_chain` work.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
