What it is

In the Linux kernel, the following vulnerability has been resolved:

virtio_pmem: Check device status before requesting flush

If a pmem device is in a bad status, the driver side could wait for

host ack forever in virtio_pmem_flush(), causing the system to hang.

So add a status check in the beginning of virtio_pmem_flush() to return

early if the device is not activated.
