From: Chao Yu Date: Mon, 15 Sep 2014 10:04:44 +0000 (+0800) Subject: f2fs: fix to clean previous mount option when remount_fs X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=26666c8a4366debae30ae37d0688b2bec92d196a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git 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.
