- If swap metadata does not fit into the KVM, reduce the number of
struct swblock entries by dividing the number of the entries by 2 until the swap metadata fits. - Reject swapon(2) upon failure of swap_zone allocation. This is just a temporary fix. Better solutions include: (suggested by: dillon) o reserving swap in SWAP_META_PAGES chunks, and o swapping the swblock structures themselves. Reviewed by: alfred, dillon
