Subject: 9p: send uevent after adding/removing mount_tag attribute
From: Michael Marineau <michael.marineau@xxxxxxxxxx>
commit e0d6cb9cd3a3ac8a3b8e5b22b83c4f8619786f22 upstream.
This driver adds an attribute to the existing virtio device so a CHANGE
event is required in order udev rules to make use of it. The ADD event
happens before this driver is probed and unlike a more typical driver
like a block device there isn't a higher level device to watch for.
