memory-failure: use a folio in me_pagecache_clean()
Patch series "Convert aops->error_remove_page to ->error_remove_folio".
This is a memory-failure patch series which converts a lot of uses of page
APIs into folio APIs with the usual benefits.
This patch (of 6):
Replaces three hidden calls to compound_head() with one visible one.
Fix up a few comments while I'm modifying this function.
