Commit d3f6f294aeadd5f88caf0155e4360808c95b3146 ("virtio-blk: always set ioeventfd during startup") has made virtio_blk_start_ioeventfd() always kick the virtqueue (set the ioeventfd), regardless of whether the BB is drained. That is no longer necessary, because attaching the host notifier will now set the ioeventfd, too; this happens either immediately right here in virtio_blk_start_ioeventfd(), or later when the drain ends, in virtio_blk_ioeventfd_attach().With event_notifier_set() removed, the code becomes the same as the one in virtio_blk_ioeventfd_attach(), so we can reuse that function.
The mentioned comit is v8.2.0-812-gd3f6f294ae, - ie, past 8.2. Is this new change still relevant for stable? Thanks, /mjt
