title: Use vim/cscope to find symbol definition in the linux kernel
body: <p>I'm using gvim/vim with cscope/ctags to find a symbol definition in the linux kernel.
  The source code is huge. when I want to search for the structure device with "tag device" command as example, vim will propose me hundred of occurrences. because it will propose global variable named device, structure's member that are named device.
  Is there anyway to improve this?
  Is it possible to tell vim/cscope/tag to look only for structure definition?</p>
