This one doesn't seem to have been suggested before :-)

At the head of your linux source run

ctags -R

in the same directory run vim (you don't need to open any file)

if you think there is only one occurrence of this routine type

:tjump <routine name>

in which case vim opens the file with it in an places the cursor at the start

if you think there might be multiple occurrences type 
:tselect <routine name>

in this case vim lists each occurrence with a number beside it.  Type the 
number you want with a carriage return.

You can do this with any identifier, not just routine names.

Once inside a source file, if you see an identify you want to find, place the 
cursor on it and type ctrl-].  this will do a tjump on the identifier.  
Again, if more that one type g ctrl-] and it will do a tselect.

You can continue to do this and build up a stack of up to 20 deep jumps.  
Ctrl-t returns you one step at a time from whence you came.
