Walt,
I made the following changes to get the kmod and client-core working with
the WALT3 branch.
While it works now, I do not know if these are the right sets of fixes..
I did a few stress tests and all tests through the vfs do seem to pass
now..
thanks,
Murali

OK, I think I fixed the small-io problem and the mkdir problem.
That only leaves the mounting problem. I've never attempted to build
the kernel interface or mount the file system (being the old goat that I
am) so that might take a bit.
I'll commit the changes I made and you can run them in the next nightly
to see if anything new pops up.
Walt
