From 732d56489f21c04f7bf60c675f7d152c9239a09c Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 29 Dec 2015 15:46:33 -0800 Subject: [PATCH] f2fs: fix f2fs_ioc_abort_volatile_write There are two rules to handle aborting volatile or atomic writes. 1. drop atomic writes - we don't need to keep any stale db data. 2. write journal data - we should keep the journal data with fsync for db recovery.
