Add the VirtioFsInit(), VirtioFsUninit(), and VirtioFsExitBoot()
functions.
In VirtioFsInit():
- Verify the host-side config of the virtio-fs device.
- Save the filesystem label ("tag") for later, from the configuration area
of the virtio-fs device.
- Save the virtio queue size for later as well.
- Set up the virtio ring for sending requests.
In VirtioFsUninit():
- Reset the device.
- Tear down the virtio ring.
In VirtioFsExitBoot():
- Reset the device.
With this patch, the UEFI connect / disconnect controller operations
involve virtio setup / teardown; they are visible in the virtio-fs
daemon's log file. The virtiofsd log also confirms the device reset in
VirtioFsExitBoot(), when an OS is booted while the virtio-fs device is
bound.
