Hi all, I want to trace the reading file of the user .I redircted the originel sys_read through another function.In that function I just used one printk statement to notify the redirction.When the module is inserted ,the message is diplayed continuosly.What went wrong? is it possible to find the users reading thru modules apart from strace.Thank u in advance for ur kind help.
