Hi, This last week I spent in tracking the fixing the bug that was causing the read/writes operations to sometimes fail. It was because of an incorrect memory address passed to memcpy(). Check the fix here [0]. After that, I spent more time testing the blkfront driver under various conditions like simultaneous I/O to multiple disks, running with low memory, copying a file multiple times and making sure the file is the same at every stage. There is one more area I would like to test: working under a scarcity of grant references. I am in the process of figuring out how to produce a scarcity of grant references. My college starts today. I will not have as much time on my hands from now onward, but I'll still try my best to complete as much work as I can before the official GSoC deadline. Of course, if any work is left after that, I will see it to the end. You can check the code here [1]. I maintain a blog on Blogger where I publish my progress every few days. Check it out if you want more details on what I'm doing [2].
