[PATCH bpf-next v2 0/3] net: struct netdev_rx_queue and xdp.h reshuffling

[Jakub Kicinski]

While poking at struct netdev_rx_queue I got annoyed by
the huge rebuild times. I split it out from netdevice.h
and then realized that it was the main reason we included
xdp.h in there. So I removed that dependency as well.

This gives us very pleasant build times for both xdp.h
and struct netdev_rx_queue changes.

I'm sending this for bpf-next because I think it'd be easiest
if it goes in there, and then bpf-next gets flushed soon after?
I can also make a branch on merge-base for net-next and bpf-next..

v2:
 - build fix
 - reorder some includes
v1: https://lore.kernel.org/all/20230802003246.2153774-1-kuba@kernel.org/

Jakub Kicinski (3):
  eth: add missing xdp.h includes in drivers
  net: move struct netdev_rx_queue out of netdevice.h
  net: invert the netdevice.h vs xdp.h dependency

[PATCH bpf-next v2 1/3] eth: add missing xdp.h includes in drivers

[Jakub Kicinski]

Handful of drivers currently expect to get xdp.h by virtue
of including netdevice.h. This will soon no longer be the case
so add explicit includes.

[PATCH bpf-next v2 2/3] net: move struct netdev_rx_queue out of netdevice.h

[Jakub Kicinski]

struct netdev_rx_queue is touched in only a few places
and having it defined in netdevice.h brings in the dependency
on xdp.h, because struct xdp_rxq_info gets embedded in
struct netdev_rx_queue.

In prep for removal of xdp.h from netdevice.h move all
the netdev_rx_queue stuff to a new header.

We could technically break the new header up to avoid
the sysfs.h include but it's so rarely included it
doesn't seem to be worth it at this point.

[PATCH bpf-next v2 3/3] net: invert the netdevice.h vs xdp.h dependency

[Jakub Kicinski]

xdp.h is far more specific and is included in only 67 other
files vs netdevice.h's 1538 include sites.
Make xdp.h include netdevice.h, instead of the other way around.
This decreases the incremental allmodconfig builds size when
xdp.h is touched from 5947 to 662 objects.

Move bpf_prog_run_xdp() to xdp.h, seems appropriate and filter.h
is a mega-header in its own right so it's nice to avoid xdp.h
getting included there as well.

The only unfortunate part is that the typedef for xdp_features_t
has to move to netdevice.h, since its embedded in struct netdevice.

Looks a bit confusing :s Could you separate then by a NL and leave a
comment near each one with the corresponding definition? Like

	return index;
}
#endif /* CONFIG_SYSFS */

#endif /* _LINUX_NETDEV_RX_QUEUE_H */

Maybe Alex could do that when applying, given that there are no more
change requests.
