From 691c6fd2a2d6b6db08b17beec5e42ab0687058c7 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Tue, 24 Sep 2013 09:26:24 +0800 Subject: f2fs: remove unneeded write checkpoint in recover_fsync_data Previously, recover_fsync_data still to write checkpoint when there is nothing to recover with normal umount image. It may reduce mount performance and flash memory lifetime, so let's remove it.
