swap partitions are never mounted, there is no swapfs for Linux (and it is
arguable whether we need one).

you are in fact wrong. You can either check the source in mm/swapfile.c
or, even easier, read the manual page for swapon(2) which explains the use
of priorities, which was in Linux since the early days of 1.3.6 (i.e. many
years ago). Basically, you can add swap devices with multiple priorities
and then a highest priority one is exhausted before using a lower-priority
one. If all areas are the same priority, then pages are allocated using
round robin algorithm, i.e. alternating between them.
