I guess this might be a case where we assume that if a filesystem does not explicitly initialise the field, it is NULL, as the system call code does check for this field to be non-NULL. If it is NULL, it returns ->ENOSYS. So, I guess, you are right in saying that there are certain per-filesystem patches that need to be installed.

So you're saying that the assumption that if a filesystem driver does not explicitly initialize the field, it is NULL, is wrong? What makes you think that?
