 different than user memory, since it can't be swapped out, which makes it
 possible to DoS the system by consuming too much of this precious resource.
 
-Some kernel memory resources may be accounted and limited separately from the
-main "kmem" resource. For instance, a slab cache that is considered important
-enough to be limited separately may have its own knobs.
-
 Kernel memory limits are not imposed for the root cgroup. Usage for the root
 cgroup may or may not be accounted.
 
-Memory limits as specified by the standard Memory Controller may or may not
-take kernel memory into consideration. This is achieved through the file
-memory.independent_kmem_limit. A Value different than 0 will allow for kernel
-memory to be controlled separately.
-
-When kernel memory limits are not independent, the limit values set in
-memory.kmem files are ignored.
-
 Currently no soft limit is implemented for kernel memory. It is future work
 to trigger slab reclaim when those limits are reached.
