Aditya, here is another example of expressions that kernel-doc cannot properly parse: include/rdma/ib_cm.h:571: warning: cannot understand function prototype: 'const char *__attribute_const__ ibcm_reject_msg(int reason); ' include/rdma/iw_cm.h:224: warning: cannot understand function prototype: 'const char *__attribute_const__ iwcm_reject_msg(int reason); ' include/rdma/rdma_cm.h:348: warning: cannot understand function prototype: 'const char *__attribute_const__ rdma_reject_msg(struct rdma_cm_id *id, int reason); ' It is probably easy to extend the current patterns of attributes in kernel-doc by just __attribute_const__, but that is of course only a quick hotfix for kernel-doc. You can start with that. But maybe you can come up with a better general solution? I see that there are multiple tools in the kernel that need to maintain a list of attributes for their internal C parsers, maybe you find a way to refactor them that they share a common file for recording the valid and supported attributes. Best regards, Lukas
