vm.swapencrypt.enable

[Patrick Latifi <patrick_(_dot_)_l_(_at_)_hermes_(_dot_)_usherb_(_dot_)_ca>]

I actually got this little surprise i actually entered the following command:
running on OpenBSD 2.8-current

# sysctl -a | grep swap
vm.swapencrypt.enable = 1
vm.swapencrypt.keyscreated = 0
vm.swapencrypt.keysdeleted = 0

I just wanted to make sure swapencrypt was turned 'on' but i realized there was
2 new sysctl variables added.  These weren't available back then in 2.7

Should vm.swapencrypt.keyscreated 0 -> 1 in order to get vm.swapencrypt fully functional?

Why were these 2 variables added? What kind of new functionnality to they provide?

Thank you for your time,

truly yours,

Patrick
