+Subject: [PATCH 2/2] cgroupfs: create /sys/fs/cgroup to mount cgroupfs on
+
+We really shouldn't be asking userspace to create new root filesystems.
+So follow along with all of the other in-kernel filesystems, and provide
+a mount point in sysfs.
+
+For cgroupfs, this should be in /sys/fs/cgroup/  This change provides
+that mount point when the cgroup filesystem is registered in the kernel.
