Hi Rusty! There are a bunch of (mostly virtio 1.0 related) fixes for virtio that need to go into 4.0 I think. virtio_blk: typo fix virtio_blk: fix comment for virtio 1.0 virtio_console: init work unconditionally virtio_console: avoid config access from irq virtio_balloon: set DRIVER_OK before using device seem ready? virtio_mmio: generation support virtio_mmio: fix endian-ness for mmio
