Best way to get a cross-reference listing...

[brian . auld]

Howdy,

I've made the push the past week, and feel that I've gotten over the initial 
emacs hump, and now feel comfortable sticking with it. I was coming from an 
intermediate vi and vslick background.

A couple questions on things I haven't figured out how to do well. 

(1) Cross-referencing
---------------------
I'm focussed on the linux kernel tree, mostly drivers. If I want to see all 
cross-references to a C symbol, so far I've found that M-x grep-find works the 
best. The problem is that I can't control what window the 'grep-find' results 
are displayed in. I usually have multiple windows open at one time, and want to 
display the result in a specific window. If I go to that window, and then enter 
the M-x grep-find command, the results are displayed in another window ... 
usually one that I don't want to be overwritten. I can always move buffer 
contents around later, but it's a pain.

Does anyone have any suggestions on (a) how to target a window with M-x 
grep-find, or an alternate way to cross-reference a code tree.

(2) etags
---------
I find if I try to etag the entire linux kernel tree using for example:

find . -name "*.[chCH]" | xargs etags -o kernel-tags

the tags never seem to be complete. What I end up doing is running something 
similar to the above for a bunch of sub-trees within the kernel that are of 
interest to me. Does anyone know why the above command doesn't seem to work for 
the entire kernel tree? Am I using the wrong command? Is there a different way 
to get a complete tags file?

Thanks,
