Currently, each ramzswap device can be assigned a separate 'backing swap' file/partition. The ramzswap driver forwards swap I/O requests to this backing swap whenever an incompressible page is found. This feature adds nearly 700 lines of code and it also duplicates much of the swapon() functionality (for example, finding swap extents and so on). Removing this code makes the driver much simpler and should help its transition from staging to stable drivers area (drivers/block/). Similar functionality may be implemented if we can implement migrating pages across swap devices but the details have not yet been worked out. Support for _partitions_ as backing swap could be retained as it requires a few lines of code only. This part can be re-introduced later if above swap migration method turns out to be infeasible. More cleanups and code comments will be added soon. Signed-off-by: Nitin Gupta <ngupta@xxxxxxxxxx>
