From 528e34593d6eff11a289ef23452c66175a340f0b Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Thu, 28 May 2015 19:15:35 +0800 Subject: [PATCH] f2fs: hide common code in f2fs_replace_block This patch clean up codes through: 1.rename f2fs_replace_block to __f2fs_replace_block(). 2.introduce new f2fs_replace_block() to include __f2fs_replace_block() and some common related codes around __f2fs_replace_block(). Then, newly introduced function f2fs_replace_block can be used by following patch.
