From 070680218379e15c1901f4bf21b98e3cbf12b527 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Wed, 14 Dec 2011 15:32:50 -0800 Subject: xen-balloon: convert sysdev_class to a regular subsystem After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel.
