How to find the definition effectively

[熊雄]

Hi everyone!

I want to use global and emacs to work with the Linux 2.6 kernel source.
When I try to find the definition of list_head (it can be found in
$linux_src/include/linux/list.h),
I was  swamped with 1151 results including definition and references.
So ,how to find the definition effectively?

Thanks!
