[Qemu-devel] [PATCH] virtio-blk: Remove the stale FIXME comment

[Fam Zheng]

By default, we have ioeventfd enabled, so the IO request processing is
in IO thread; in the vcpu thread, guest mode is returned to as quickly
as possible, and completion is delivered via irqfd. Therefore this
comment from the initial implementation is barely relevant.
