From e0d6cb9cd3a3ac8a3b8e5b22b83c4f8619786f22 Mon Sep 17 00:00:00 2001 From: Michael Marineau Date: Sun, 11 Aug 2013 00:53:45 -0400 Subject: 9p: send uevent after adding/removing mount_tag attribute 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.
