    The pre-existing sysfs interfaces which take explicit namespace
    argument are weird in that they place the optional @ns in front of
    @name which is contrary to the established convention.  For example,
    we end up forcing vast majority of sysfs_get_dirent() users to do
    sysfs_get_dirent(parent, NULL, name), which is silly and error-prone
    especially as @ns and @name may be interchanged without causing
    compilation warning.
    
    This renames sysfs_get_dirent() to sysfs_get_dirent_ns() and swap the
    positions of @name and @ns, and sysfs_get_dirent() is now a wrapper
    around sysfs_get_dirent_ns().  This makes confusions a lot less
    likely.
    
    There are other interfaces which take @ns before @name.  They'll be
    updated by following patches.
    
    This patch doesn't introduce any functional changes.
    
    v2: EXPORT_SYMBOL_GPL() wasn't updated leading to undefined symbol
        error on module builds.  Reported by build test robot.  Fixed.
