This is a feature request, to add functionality to the kernel, not to address any bug. The request is to add patches for the 'zpool' api to allow zswap to use either the zbud or zsmalloc storage backends. Without the zpool patches, zswap can only use zbud, which provides only 2:1 storage compression, while with the zpool patches, zswap can use zsmalloc, which provides much higher storage compression, closer to the actual average page compression ratio.

This bug was fixed in the package linux - 3.16.0-11.16
