len(CacheMode) should be enough (it doesn't count DEFAULT as separate entry)

The title is quite ambiguous. Sounds like validating a module which is used by a counter. If 'module used by' is a name of a counter, then do what I just did - put it in ' '.

| - Cannot remove OpenCAS kernel modules when usage counter is not 0. | ||
| - OpenCAS increase and decrease cas_cache usage counter. | ||
| - OpenCAS usage counter is equal to amount of caches. |

'number' instead of 'amount' ('amount' is for uncountable nouns)
