From 871f599f4a869d24ef98b0217f19f0cc55ff59ac Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 9 Jan 2015 16:27:17 -0800 Subject: [PATCH] f2fs: avoid infinite loop on cp_error If cp_error is set, we should avoid all the infinite loop. In f2fs_sync_file, there is a hole, and this patch fixes that.
