From 2d834bf9ac8e40d9ae2a2dcde2348bd028f87ec4 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 23 Jan 2015 18:33:46 -0800 Subject: f2fs: support norecovery mount option This patch adds a mount option, norecovery, which is mostly same as disable_roll_forward. The only difference is that norecovery should be activated with read-only mount option. This can be used when user wants to check whether f2fs is mountable or not without any recovery process.
