From 71cb4afff80cee2b0f0dfda32f55e4e8d4f1153d Mon Sep 17 00:00:00 2001 From: Hsiang Kao Date: Sun, 24 Sep 2017 02:45:42 +0800 Subject: [PATCH] f2fs: allow readpages with NULL file pointer Keep in line with the other Linux file system implementations since page_cache_sync_readahead supports NULL file pointer, and thus we can readahead data by f2fs itself without file opening (something like the btrfs behavior).
