I have a problem in my custom arm machine to use 9p fs as a rootfs.

9p command line i qemu:

-device virtio-9p-device,fsdev=host_fs,mount_tag=hostfs -fsdev local,id=host_fs,security_model=none,path=/work/rootfs

Kernel cmd line:

--append "root=hostfs rootfstype=9p rootflags=trans=virtio noinitrd console=ttyS3,115200"

Device tree entry:

        virtio: virtio_mmio@ff0a4000 {
            compatible = "virtio,mmio";
            reg = <0xff0a4000 0x200>;
            interrupts = <0 72 1>;
            status = "okay";
        };


 I can mount this fs from kernel using fstab entry:
hostfs               /mnt/host            9p         trans=virtio          0  0

Do you have any idea what am I doing wrong?

Thanks,
Marcin
