  In-memory mode was never meant to support legacy mode, because we
cannot sort anonymous pages anyway.

Fixes: 72b49ff623c4 ("mem: support --in-memory mode")

This is a general comment, as it is consistent with the style of the
file. I generally prefer not splitting error strings into multiple lines
even if it is longer than 80 chars, because it makes grepping for the 
error string more difficult.

I agree in general, however in this particular case the string is 
ungreppable (it is a word now!) anyway because it's split into a few pieces.
