usually I do
[om@pandatest1 /usr/src/linux-2.4]$ find -name '*.[chsS]' > filst
[om@pandatest1 /usr/src/linux-2.4]$ gvim flist # edits the file list so
taht it will not contain any unwanted files for me
[om@pandatest1 /usr/src/linux-2.4]$ ctags -L flist
[om@pandatest1 /usr/src/linux-2.4]$ cscope -i flist
in the ~/.vimrc add the following line.
se tags=/usr/src/linux-2.4/tags
Again, trivial knowledge. but useful tip.
bye
Om.
