I realize that VDISK is special in the world of Linux, but why doesn't
someone give us the option of preventing this? Looks to me like adding one
line in swapfile.c would allow pages to cluster at the beginning of a disk
instead of running to the end and starting over at the beginning.
si->flags += SWP_SCANNING;
---> goto lowest;
if (unlikely(!si->cluster_nr)) {
So, just make this a configurable option via procfs and let us decide. :-)
