First of all, I apologize for the delay. I have now returned from my vacation,
had a few days to settle in and explain to my neighbours that I'm not dead (!).
Anyways, on to the interesting stuff.
On the surface, the status of things is mostly the same as in my last report,
with a few bugs less. I thought I had dedicated more than enough time for
bugfixing, but that turned out to not be the case. This is partly due to the
slower development cycle when testing natively (compile, copy driver to image,
boot virtual machine, test, repeat), and the bugs only showing up after doing
several resizes with other IO going on. All the bugs of this kind that I know
about have been eliminated.
To summarize the things I have accomplished during the summer:
- Resize support in BFS driver, save for vnode mapping and growing a full
- Getting the resizing "pipeline" from userspace to driver to a working
state (still needs some checking to verify that it's robust).
