From 1ecc0c5c50ce8834f7e35b63be7480bf1aaa4155 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Fri, 23 Sep 2016 21:30:09 +0800 Subject: f2fs: support configuring fault injection per superblock Previously, we only support global fault injection configuration, so that when we configure type/rate of fault injection through sysfs, mount option, it will influence all f2fs partition which is being used. It is not make sence, since it will be not convenient if developer want to test separated partitions with different fault injection rate/type simultaneously, also it's not possible to enable fault injection in one partition and disable fault injection in other one. >From now on, we move global configuration of fault injection in module into per-superblock, hence injection testing can be more flexible.
