From: Greg Kroah-Hartman Date: Tue, 6 Nov 2007 18:36:58 +0000 (-0800) Subject: kobject: convert kernel_kset to be a kobject X-Git-Tag: v2.6.25-rc1~1243^2~100 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0ff21e46630abce11fdaaffabd72bbd4eed5ac2c;p=linux-2.6 kobject: convert kernel_kset to be a kobject kernel_kset does not need to be a kset, but a much simpler kobject now that we have kobj_attributes. We also rename kernel_kset to kernel_kobj to catch all users of this symbol with a build error instead of an easy-to-ignore build warning.
