Hi Priya,

Please make use of a single thread for one topic. There was another thread
by you on the same topic. Anyways, I am replying to this one.

Greg has asked questions that you should ask yourself before going on with
choosing one approach.

I had suggested you using kern_path() earlier, since it doesn't makes use
of nameidata, but as you are telling its not working too. Here I would like
to know the actual context of the approach so as to figure out if something
I know that can work for you or maybe you shouldn't be doing it that way.

Enjoy life,
Rohan
