Subject: [PATCH bpf-next 0/2] Two XSKMAP improvements

This series add two improvements for the XSKMAP, used by AF_XDP
sockets.

1. Automatic cleanup when an AF_XDP socket goes out of scope. Instead
   of manually cleaning out the "released" state socket from the map,
   this is done automatically.

2. The XSKMAP did not honor the BPF_EXIST/BPF_NOEXIST flag on insert.


Thanks,
Björn


Björn Töpel (2):
  xsk: remove AF_XDP socket from map when the socket is released
  xsk: honor BPF_EXIST and BPF_NOEXIST flags in XSKMAP
