It is still dymanic due the fact that kswapd will be run not depending on a
wall clock, but on problematic allocations done.
(i.e. inactive_target looses its meaning for the VM since it measures
pages/second but second is no more a base for kswapd runs...
both mean - I want to have this amount of reclaimable pages until the next
kswapd run...)
