The patch titled
mm: create /sys/kernel/mm
has been removed from the -mm tree. Its filename was
mm-create-sys-kernel-mm.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: mm: create /sys/kernel/mm
From: Nishanth Aravamudan <nacc@xxxxxxxxxx>
Add a kobject to create /sys/kernel/mm when sysfs is mounted. The kobject
will exist regardless. This will allow for the hugepage related sysfs
directories to exist under the mm "subsystem" directory. Add an ABI file
appropriately.
