Hi Shashidhar,
Unfortunately, I have to tell you that an implementation like this is
inappropriate for a number of reasons. My feeling is that most
importantly you should instead have the test logic entirely in user
space and only call the existing ioctl in the kernel. This would
make the entire patch obsolete, so I'm not commenting on the other
problems.
What has lead you to implementing the individual test cases in the
kernel?
