4 | Subject: [PATCH] cgroupfs: create /sys/fs/cgroup to mount cgroupfs on | ||
5 | |||
6 | We really shouldn't be asking userspace to create new root filesystems. | ||
7 | So follow along with all of the other in-kernel filesystems, and provide | ||
8 | a mount point in sysfs. | ||
9 | |||
10 | For cgroupfs, this should be in /sys/fs/cgroup/ This change provides | ||
11 | that mount point when the cgroup filesystem is registered in the kernel. | ||
