    f2fs: support fs shutdown · 1abff93d
    Jaegeuk Kim 提交于
    This patch introduces a generic ioctl for fs shutdown, which was used by xfs.
    
    If this shutdown is triggered, filesystem stops any further IOs according to the
    following options.
    
    1. FS_GOING_DOWN_FULLSYNC
     : this will flush all the data and dentry blocks, and do checkpoint before
       shutdown.
    
    2. FS_GOING_DOWN_METASYNC
     : this will do checkpoint before shutdown.
    
    3. FS_GOING_DOWN_NOSYNC
     : this will trigger shutdown as is.
