I wouldn't want to call it swap, as this carries with it block-io
connotations. It's really mmap on flash.
Yes it is really mmap on flash. But you are "swapping" pages from RAM
to be mmap'ed on flash. Also the flash-io complexities are similar to
the block-io layer. I think "swap on flash" is fair. Though that
might be confused with making swap work on a NAND flash, which is very
much like the current block-io approach. "Mmappable swap on flash" is
more exact, I suppose.

Are you suggesting to go through the block layer to reach the flash?
Well the obvious route would be to have this management layer use the
MTD, I can't see anything wrong with that.

Correct.
BTW, you may want to have a look at my "[RFC] VM: I have a dream..." thread.
Interesting. This idea does allow for swap to be access directly.
