Hi Rafael, After merging the pm tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: "configfs_unregister_subsystem" [samples/configfs/configfs_sample.ko] undefined! ERROR: "configfs_register_subsystem" [samples/configfs/configfs_sample.ko] undefined! ERROR: "config_group_init" [samples/configfs/configfs_sample.ko] undefined! ERROR: "config_item_init_type_name" [samples/configfs/configfs_sample.ko] undefined! ERROR: "config_group_init_type_name" [samples/configfs/configfs_sample.ko] undefined! ERROR: "configfs_undepend_item" [fs/ocfs2/cluster/ocfs2_nodemanager.ko] undefined! ERROR: "config_item_put" [fs/ocfs2/cluster/ocfs2_nodemanager.ko] undefined! ERROR: "config_item_init_type_name" [fs/ocfs2/cluster/ocfs2_nodemanager.ko] undefined! ... and many more ... Presumably (maybe?) caused by commit 0bf54fcd9504 ("ACPI: add support for configfs") though it is not obvious why this should be a problem. I have used the version of the pm tree from next-20160708 for today. -- Cheers, Stephen Rothwell -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
