If plenty of free memory is available, it will stop writing new stuff to
swap.  Old pages out on swap will stay there until accessed, until their
processes die, or until the swap area is deleted.  If there's enough
memory then you can delete swap:

  # swap -d /dev/swap

After a suitable amount of time (all paged-out pages have to be read
in), `swap -l` will show it gone.  You can then re-add it,

  # swap -a /dev/swap

If you have other swap areas then this will be more complex.  Also if
you're using an offset, you'll need to specify it in both -d and -a
commands.  I don't know what people would be using a swap offset for in
2002, but who knows...

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
