I don't have a specific procedure to test this, but I believe I showed
you proof that it's a good idea. I'm sure the reason discard isn't the
default is because people actually use swap on SSD, and repeated
discard commands will wear the flash storage too much.
If you want to merge it, fine. If you don't, it's fine too, I'll just
keep it in my tree.

Cheers,
Rui
