As Jani suggested we need a commit message here. Would something
like this work for you?
"
We forget to free 'pages' after checking for overflow. Be sure to
properly free the allocated memory before exiting the
fake_free_pages() function.
"
If it's OK for you, then I can add this message and fix the blank
space before pushing this patch.
In any case:
