Sometimes, tag may be helpful and quick.
e.g
cd /the/path/to/kernel/src
ctags -R *
if we want to see the definition of iget(), try
vi -t iget
in linux-2.4.7-10, iget() has multiple definition. you can iterate them with ":tn" (for next tag) and
":tp" (for prev tag).
You can even ignore case, take as an example, if you want to examine the def of function My_Func(),
but at that time, you are not quite sure whether the 1st char of My_Func() is in upper case of lower case.
you can
o. invoke vi
o. if tags does not reside at `pwd`, invoke this command in vi:
:set tag=/the/path/to/the/pertinent/tags
o. examine the 1st definition with this vi command: :ta my_func
The command "etags" also works fine with emacs. However, since I am rather stupid,
I am clusy with that excellent tool.

Hi,
you can try this command: get -r \"getifaddrs\" /usr/src/linux
