Just wondering if there is any further news or tests that I might be

I have been working on speed improvements for blkfront/blkback, and
submitted the first RFC series of patches last week, which can be found
at http://thread.gmane.org/gmane.linux.kernel/1448584. This is still a
WIP, so if you want to test them please be aware there might be hidden
bugs. I've also pushed them to a branch in my git repo:

git://xenbits.xen.org/people/royger/linux.git xen-block-indirect

You will need to recompile both the Dom0/DomU kernels (if they are not
the same) if you want to test them.

Hmm - how will this react with using say, a stock kernel in the DomU (ie EL6.3 kernel) but these changes in the Dom0?
