Are you talking about a user who is running a process that
makes a call into your kernel module() to access a file?
If so, try getuid()/geteuid().

If you are talking about trying to find out who has read one
of the source files for a kernel module, I don't believe that
is in general possible.

Thanks for reply William.
user id i got simply putting current ->uid in my open call of module.
But now looking how to get username from this uid.
