Bug#4289: mount's swapon command doesn't have the "-s" option

[Austin Donnelly <Austin.Donnelly@cl.cam.ac.uk>]

Package: mount
Version: 2.5j-1.1

In many traditional unices, swapon can take a "-s" option. This means
list the partition (or files) currently in use. Linux's swapon doesn't
have this option, but it would be nice if it did.

I don't think this information is made available outside the kernel;
perhaps it should be a file in /proc?

(This bug should probably be forwarded upstream.)
