====================
pull-request: bpf 2018-08-18

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix a BPF selftest failure in test_cgroup_storage due to rlimit
   restrictions, from Yonghong.

2) Fix a suspicious RCU rcu_dereference_check() warning triggered
   from removing a device's XDP memory allocator by using the correct
   rhashtable lookup function, from Tariq.

3) A batch of BPF sockmap and ULP fixes mainly fixing leaks and races
   as well as enforcing module aliases for ULPs. Another fix for BPF
   map redirect to make them work again with tail calls, from Daniel.

4) Fix XDP BPF samples to unload their programs upon SIGTERM, from Jesper.
