From 12377024719f08b7411afe9fc0169b13808dfefa Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Mon, 25 May 2015 18:03:38 +0800 Subject: [PATCH] f2fs: avoid duplicated code by reusing f2fs_read_end_io This patch tries to clean up code because part code of f2fs_read_end_io and mpage_end_io are the same, so it's better to merge and reuse them.
