From 36abef4e796d382e81a0c2d21ea5327481dd7154 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 3 Jun 2016 19:29:38 -0700 Subject: f2fs: introduce mode=lfs mount option This mount option is to enable original log-structured filesystem forcefully. So, there should be no random writes for main area. Especially, this supports host-managed SMR device.
