The patch titled
build errors: uevent with CONFIG_SYSFS=n
has been removed from the -mm tree. Its filename was
build-errors-uevent-with-config_sysfs=n.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: build errors: uevent with CONFIG_SYSFS=n
From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>
Fix source files to build with CONFIG_SYSFS=n. module_subsys is not
available.
