[kernel-xen] Thoughts regarding bcache.

Hi all,

I've been seriously thinking lately about rolling 'bcache' into the 
kernel-xen kernel.

Details about bcache can be found here:

In a nutshell, it allows you to create a new volume (say a RAID6) and 
have a standard SATA SSD drive connected and used as a writeback cache. 
This means in situations where a RAID6 is in use to host DomU 
filesystems, the SSD cache could dramatically increase both read and 
write operations.

bcache is currently in the process of being rolled into the upstream 
kernel, but it may be some time until this is completed.

What are peoples thoughts on this?
