cd /usr/src/linux find include -type f | xargs grep 'struct task_struct' | more Lots of hits. One of those is the definition of the structure. Study it and learn from that. The rest are where other things refer to the structure - much can be learned from studying what *else* refers to it and why. Enjoy.
