I don't think it's that bad, since almost every header ends up including linux/list.h indirectly at the moment. A little bit of scripting to find the headers that reference 'struct list_head' but don't also include linux/list.h reveals this relatively short set that would need to include the new header: > include/keys/asymmetric-parser.h > include/linux/dynamic_debug.h > include/linux/genalloc.h > include/linux/gpio/machine.h > include/linux/hiddev.h > include/linux/iio/iio-opaque.h > include/linux/iio/sysfs.h > include/linux/input/touch-overlay.h > include/linux/irq_poll.h > include/linux/iscsi_boot_sysfs.h > include/linux/kcore.h > include/linux/kcsan-checks.h > include/linux/kcsan.h > include/linux/lockdep_types.h > include/linux/logic_pio.h > include/linux/maple.h > include/linux/mfd/iqs62x.h > include/linux/mlx5/macsec.h > include/linux/mount.h > include/linux/mtd/map.h > include/linux/mtd/nand-qpic-common.h > include/linux/mtd/partitions.h > include/linux/mutex_types.h > include/linux/nfs_fs_i.h > include/linux/of_iommu.h > include/linux/parport_pc.h > include/linux/pinctrl/pinctrl.h > include/linux/plist_types.h > include/linux/pm_wakeup.h > include/linux/reboot-mode.h > include/linux/shm.h > include/linux/smpboot.h > include/linux/sunrpc/xprtmultipath.h > include/linux/usb/audio.h > include/linux/workqueue_types.h > include/linux/zpool.h > include/net/bluetooth/hci_sync.h > include/net/bluetooth/l2cap.h > include/net/bluetooth/rfcomm.h > include/net/dcbnl.h > include/sound/i2c.h > include/sound/soc-jack.h > include/target/iscsi/iscsi_transport.h > include/video/udlfb.h A lot of these don't have any #include statements at all, which indicates that they expect to only be included in places where the dependencies are already visible.
