  *      To avoid global state use 8 different call vectors.
  *      Each CPU uses a specific vector to trigger flushes on other
  *      CPUs. Depending on the received vector the target CPUs look into
- *      the right per cpu variable for the flush data.
+ *      the right array slot for the flush data.
  *
  *      With more than 8 CPUs they are hashed to the 8 available
  *      vectors. The limited global vector space forces us to this right now.
