Thanks everyone for viewing and trying to think over it. I got my solution for this strange problem. So that none of u face same problem i'll tell what happened.
I created my kernel module and created a patch (mymodule.patch file) for it. Next I went through the patch-o-matic and learnt how to add ones own new patches to the already existing ones. Now I created all files required to patch makefile, config.in file etc. But to my surprise when I applied this patch last two lines were not included in the C file that resulted from patch. These two lines contained module initialisation and exit code. And so upon calling from user space though the module was loaded but it was loaded as tainted module. Luckily on going through again and again I could find the mistake and then rectified it.
So this way i got rid of problem but still thanks to u all for atleast looking into my problem.
