    f2fs: support configuring fault injection per superblock · 1ecc0c5c
    Chao Yu authored
    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.
