[PATCH bpf-next 0/8] AF_XDP follow-up patches, uapi and cleanups

["Björn Töpel" <bjorn.topel@gmail.com>]

From: Björn Töpel <bjorn.topel@intel.com>

This the second follow-up set. The first four patches are uapi
changes:

* Removing rebind support
* Getting rid of structure hole
* Removing explicit cache line alignment
* Stricter bind checks

The last patches do some cleanups, where the umem and refcount_t
changes were suggested by Daniel.

* Add a missing write-barrier and use READ_ONCE for data-dependencies
* Clean up umem and do proper locking
* Convert atomic_t to refcount_t

Björn Töpel (7):
  xsk: remove rebind support
  xsk: fill hole in struct sockaddr_xdp
  xsk: remove explicit ring structure from uapi
  samples/bpf: adapt xdpsock to the new uapi
  xsk: add missing write- and data-dependency barrier
  xsk: simplified umem setup
  xsk: convert atomic_t to refcount_t

Magnus Karlsson (1):
  xsk: proper queue id check at bind
