I tried to do that a while ago, when I was trying to use it for
name_to_dev_t()ing in swsusp somewhere.


>From my notes at the time:

  a) It barfs if /sys is already mounted.

  b) Fix that, mkdir and mount barf because it needs set_fs(KERNEL_DS)

  c) Fix that, it barfs because name_to_dev_t is just broken.  It is
     accessing the wrong pathnames in /sys.

I think it needs a bit of help.
