[Cocci] [RFC 0/2] coccinelle: extend test coverage

[mcgrof@kernel.org (Luis R. Rodriguez)]

I wanted to extend tests coverage for coccinelle but noticed
that tests are limited to single c file, these are attached
to respective .res files, but this also means that you have
a direct relationship and requirement between tests from
a single C file and a respective cocci file.

To go wild we want to be able to support really complex
types of examples. Fortunatley the backports project has
been using Coccinelle extensively daily, when a backports
developers needed to replace a series of patches with a
Coccinelle patch pycocci was extended to provide 
SmPL <--> Patch equivalence support. We can easily take
advantage of this to extend Coccinelle test cases way
beyond a single C file, but to more complex real life
style projects.

I don't think we should convert all test cases to this
new mechanism but, I'd like to see what are folks' thoughts
over using pycocci SmPL <--> Patch equivalence proof support
to help expand the tests cases for Coccinelle.
