This patch adds the --add-ramdisk-swap option, which when specified,
creates and activiates swap space on ramdisk for the duration of
the positive pool resize. If the ramdisk size on the system is not
as big as the huge page size, then swap is initialized on multiple
ramdisks.

Adding the --perist option which is specified with --add-ramdisk-swap
or --add-temp-swap, to make the swap space created, permanent after the
pool resize is completed.

I've been reading the code maybe a little explanation could help?

So if you can't use any lib
The string returned from add_ramdisk_swap points to local memory that
can be overwritten after return. This patch makes a global string
ramdisk_list which is used to store the list of ramdisks swap is
initialized on.
