Yes, we remove the data from memory any time we remove a mapping but
we only remove mappings when Mach evicts the data.

Just a small techical correction: we remove mapping only when we are remapping page to contain another block. So when page is evicted, it continues to map the same disk block until ext2fs decides that we want this page to hold another block (only if page is still evicted, of course).
