I am not familiar with out-of-tree development but I guess that inI decided to skip doing this in V2 of the patch. I did a very quick test and cocci didn't seem to like two -I flags on one command line.
that case we should
also add a "-I $KBUILD_EXTMOD/include" ?
The use of -I by Coccinelle depends on the other options (like
-include_headers or -all_includes).
Such options are retrieved from the comments in the cocci files.
So the need for -I depends on the semantic patch you consider. I think
it is thus better
to be "exhaustive" in that case.
Julia, is there any performance problem in doing so ?
