Date: Mon, 15 Sep 2014 18:04:44 +0800 From: Chao Yu <chao2.yu@...sung.com> To: Jaegeuk Kim <jaegeuk@...nel.org>, Changman Lee <cm224.lee@...sung.com> Cc: linux-f2fs-devel@...ts.sourceforge.net, linux-kernel@...r.kernel.org Subject: [f2fs-dev][PATCH 4/5] f2fs: fix to clean previous mount option when remount_fs In manual of mount, we descript remount as below: "mount -o remount,rw /dev/foo /dir After this call all old mount options are replaced and arbitrary stuff from fstab is ignored, except the loop= option which is internally generated and maintained by the mount command." Previously f2fs do not clear up old mount options when remount_fs, so we have no chance of disabling previous option (e.g. flush_merge). Fix it.
