Would you like to avoid the repetition of a SmPL key word here?

+virtual patch, context, org, report, selfcheck

I suggest to reconsider the usage of the function “cocci.files()”.
Can such a script rule determine for which file it should perform data processing?

Can the following code variant be a bit nicer?

+            sys.stdout.write('SELF-CHECK: The pattern does not match definitions {} in file {} any more.\n' \
+                             .format(not_found, efile))
