 Description   

The Memory Use section of the WiredTiger Storage Engine page incorrectly states that "Data in the filesystem cache is compressed."

This is only true if the data files themselves are using WiredTiger compression (Snappy or zLib). If they are uncompressed, so too is the data in the FS cache.
