From 3e2faa085448d5c478ebc9d5f6cb4d822467f4d7 Mon Sep 17 00:00:00 2001 From: Fabian Frederick Date: Wed, 6 Aug 2014 16:04:55 -0700 Subject: mm/readahead.c: remove unused file_ra_state from count_history_pages count_history_pages does only call page_cache_prev_hole in rcu_lock context using address_space mapping. There's no need to have file_ra_state here.
