virtio: Inject virtio-blk interrupt quickly
Current blk interrupt is injected into guest after device handle a batch of requests. While this patch injects interrupt at the end of each request. So guest block will get much more interrupts and could handle request more quickly. With this patch, the guest fio read test improves 13%, while fio write doesn't get better. BUG=none TEST=run fio_read and fio_write in guest Change-Id: Ib0bd23e624dfc5d940d6cc124468b898d8ba128e Signed-off-by: Xiong Zhang <xiong.y.zhang@intel.corp-partner.google.com> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/2008338 Reviewed-by: Daniel Verkamp <dverkamp@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com>
