[acme@...a linux-2.6.23-rc9-rt1]$ find . -name "*.c" | xargs grep
'module_param(.\+debug,' | wc -l
112
[acme@...a linux-2.6.23-rc9-rt1]$ find . -name "*.c" | xargs grep
'module_param(debug,' | wc -l
233
[acme@...a linux-2.6.23-rc9-rt1]$

I think that helping ctags to find the definition for the debug variable
to see, for instance, if it is a bitmask or a boolean without having to
chose from tons of 'debug' variables is a good thing.
