From c34f42e2cb2d27650549306de5ff36839e9177d6 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Wed, 23 Dec 2015 17:50:30 +0800 Subject: f2fs: report error of do_checkpoint do_checkpoint and write_checkpoint can fail due to reasons like triggering in a readonly fs or encountering IO error of storage device. So it's better to report such error info to user, let user be aware of failure of doing checkpoint.
