[PATCH] mm: add a new function (needed for swap suspend)
This adds the function get_swap_page_of_type() allowing us to specify an index
in swap_info[] and select a swap_info_struct structure to be used for
allocating a swap page.
This function (or another one of similar functionality) will be necessary for
implementing the image-writing part of swsusp in the user space. It can also
be used for simplifying the current in-kernel implementation of the
image-writing part of swsusp.
