Question related to nfs(network file system) in linux kernel.
Hi All, I want a requirement to intercept rpc call to nfs(network file system) or get hold of nfs buffer in kernel space and get data from the buffer to print it. I went through the kernel code .But i didn't get it .I am beginner in linux kernel. Please give your suggestions. Thanks in Advance. Siva Kumar

First thing to do is take a step back. What problem are you trying to solve by intercepting the RPC and printing the data? (Hint - print it to *where*? Is the destination a feasible target if you're doing NFS over a 10Gbit adapter? Etc etc..)

You probably should look for xpo structures of TCP and UDP . plus sk_data_ready callback. Been a while since I saw NFS but that's the place.
