    sysfs: fix namespace refcnt leak · fed95bab
    Li Zefan authored
    As mount() and kill_sb() is not a one-to-one match, we shoudn't get
    ns refcnt unconditionally in sysfs_mount(), and instead we should
    get the refcnt only when kernfs_mount() allocated a new superblock.
    
    v2:
    - Changed the name of the new argument, suggested by Tejun.
    - Made the argument optional, suggested by Tejun.
    
    v3:
    - Make the new argument as second-to-last arg, suggested by Tejun.
