- * This local function updates the total number of pages in level 0 DQDT node,

+ * These two functions can be called by any thread running in any cluster.
+ * They increment/decrement the total number of 4 Kbytes pages allocated in a cluster
+ * identified by the <cxy> argument, as specified by the <order> argument. The level 0

  * They are called by PPM on each physical memory page allocation or release.
