From 6c0b13519d1c755d874e82c8fb8a6dcef0ee402c Mon Sep 17 00:00:00 2001 From: Johannes Weiner Date: Mon, 21 Sep 2009 17:02:59 -0700 Subject: mm: return boolean from page_is_file_cache() page_is_file_cache() has been used for both boolean checks and LRU arithmetic, which was always a bit weird. Now that page_lru_base_type() exists for LRU arithmetic, make page_is_file_cache() a real predicate function and adjust the boolean-using callsites to drop those pesky double negations.
