I clean UFS freed disk blocks, but i don't know how to do it from
swap_pager. :( there are some kva to phisical mapping, which i do not
understand. So i thought someone could point me how can write block from
swap_pager to the disk or where can i read more info (except McKusicks'
book and kernel sources).
PS. I can make patch, which wipes files(freed blocks) upon deletion for
-current, if someone is interested.
