In my opinion it's not obsolete, because we don't have to remove the
fragment from the compresse cache and store it in the swap (regardless
if it's in ramdisk, for example), decreasing variables that account
for compression success. However, the current vswap code isn't very
stable and needs improvement, so we should give a second thought if
the effort is worth its benefit.
