How to browse the code

[Code Soldier1]

Folks,

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.

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.

Thanks a lot.
