Hi Dave,
the kernel will automagically take care of that double allocation: as soon
as your swap space is 50% full,
the kernel will free the swap slot on paging in. Note that this does'nt
save you a single memory page
though, since the very same memory content will now be billed as anonymous
memory rather than
swap cache.
with kind regards

SwapCache

Is there a way to disable or limit the amount of SwapCache? I understand
it's function, but the double allocation of these pages is causing my low
memory alerts to trip.
I can remove the swap copy with a swapoff/swapon. Is there a more elegant
way to remove?
