Is this a bug in systemtap, or in how Module.markers is getting\n\u003e built? And is there a file that contains the equivalent information\n\u003e for markers located in non-modules code?\n\nI think the problem comes from \"markers: fix duplicate modpost entry\"\n(commit d35cb360c29956510b2fe1a953bd4968536f7216)\n\nEspecially :\n\n -
