From ff45fc3ca0f3c38e752d75f71b8d8efcf409e42d Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 3 Jun 2020 16:01:09 -0700 Subject: mm: simplify calling a compound page destructor None of the three callers of get_compound_page_dtor() want to know the value; they just want to call the function. Replace it with destroy_compound_page() which calls the dtor for them.
