    sysfs, kernfs: introduce kernfs_create_dir[_ns]() · 93b2b8e4
    Tejun Heo authored
    Introduce kernfs interface to manipulate a directory which takes and
    returns sysfs_dirents.
    
    create_dir() is renamed to kernfs_create_dir_ns() and its argumantes
    and return value are updated.  create_dir() usages are replaced with
    kernfs_create_dir_ns() and sysfs_create_subdir() usages are replaced
    with kernfs_create_dir().  Dup warnings are handled explicitly by
    sysfs users of the kernfs interface.
    
    sysfs_enable_ns() is renamed to kernfs_enable_ns().
    
    This patch doesn't introduce any behavior changes.
    
    v2: Dummy implementation for !CONFIG_SYSFS updated to return -ENOSYS.
    
    v3: kernfs_enable_ns() added.
    
    v4: Refreshed on top of "sysfs: drop kobj_ns_type handling, take #2"
        so that this patch removes sysfs_enable_ns().
