    [PATCH] swsusp: introduce the swap map structure · 7088a5c0
    Rafael J. Wysocki authored
    This patch introduces the swap map structure that can be used by swsusp for
    keeping tracks of data pages written to the swap.   The structure itself is
    described in a comment within the patch.
    The overall idea is to reduce the amount of metadata written to the swap and
    to write and read the image pages sequentially, in a file-alike way.  This
    makes the swap-handling part of swsusp fairly independent of its
    snapshot-handling part and will hopefully allow us to completely separate
    these two parts in the future.
    This patch is needed to remove the suspend image size limit imposed by the
    limited size of the swsusp_info structure, which is essential for x86-64
    systems with more than 512 MB of RAM.
