Hi,

I might be missing something but doesn't this break every
SWAP partition that was created with something other than
MIN_PAGE_SIZE?


It does. I was thinking we could work around it in ppc64 (64kB is quite
new), but I forgot there are options on sparc64 to change the page size :)

The other option is to create a v3 swap format that doesnt use any
PAGE_SIZE parameters.

The best thing to do would be to look for the magic both at PAGE_SIZE (for compatibility) and MIN_PAGE_SIZE (for sanity.)
