hum, sizes reported depend of `swd_bsize', which depend of
`statvfs->f_iosize' which could be different of DEV_BSIZE, but who want
to have swap device on CD-rw :). btw, DEV_BSIZE / 1024 is 1/2, but I'll
update the patch anyway :)
swd_bsize is only used by files anyway. you want to report the
se_nblks/se_inuse which are stored in DEV_BSIZE units.
btw, you should perhaps skip swapent's with SWF_FAKE set in the
se_flags word.
