I remember me having worked on that but I cannot find any patchI'll submit what I have done as a new thread / patch series. I've not done much testing with it and am certainly not any kind of build system expert, but it has worked well for me so far :) A few more people trying it out / testing it would be a great idea.
about it so your patch is more that welcome. Some users have requested it
some months ago.
As far as I can remember, with "M=" you can not use $srctree only but still
need it for the -I for instance. I think I then run into a situation where I
have an ambiguity about how to setup the flags for coccinelle, but I am sure
about the reason I dropped my patch. Maybe I don't know well enough the build
system and options...
So, don't hesitate to submit your patch.
Does it also update the Documentation/coccinelle.txt accordingly ?It will :)
