    cgroup: fix to allow mounting a hierarchy by name · 0d19ea86
    Li Zefan authored
    If we mount a hierarchy with a specified name, the name is unique,
    and we can use it to mount the hierarchy without specifying its
    set of subsystem names. This feature is documented is
    Documentation/cgroups/cgroups.txt section 2.3
    
    Here's an example:
    
    	# mount -t cgroup -o cpuset,name=myhier xxx /cgroup1
    	# mount -t cgroup -o name=myhier xxx /cgroup2
    
    But it was broken by commit 32a8cf23
    (cgroup: make the mount options parsing more accurate)
    
    This fixes the regression.
