Hi Dan,
I manually walked through the driver code and spotted the issue. But
this morning I was able to get an extra module to verify my patch on

I also wonder if you have anything else unusual in your

on the same rotating disk as source and target of the kernel build,
the default install for a RHEL6 system)?

Do we need a Unix domain socket equivalent to openat()?
I don't think so. The name is just a file system indexing trick, it's not
really the socket proper. It's little more than ascii string with
permissions attached - indeed we also support an abstract name space
