I am looking for something that can list all the places that a certain field of a certain structure is used. For example, sk_buff has a field called destructor, but so do many other data structures. How do I search for places where just the destructor field of sk_buff.

I think lxr has an identifier & free-text search (powered by google). If that doesn't do it for you, you can go "old school" and try cscope maybe? HTH, -mandeep

Thanks a lot.

Can you tell me how to effectively browse linux kernel code. I am familiar with lxr etc but they do not do what I want or atleast I do not know how to.

Ask yourself *how* is the destructor invoked ? You can find *how* here: SKB socket accounting <http://vger.kernel.org/%7Edavem/skb_sk.html> So now if you run: find . -name '*.c' | xargs grep -r -F "skb->destructor" you will have what you are looking for :) Hope this helps and this will help: http://vger.kernel.org/~davem/skb.html <http://vger.kernel.org/%7Edavem/skb_sk.html> Aruna
