Hi David,

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

The main changes are:

1) Fix xsk map update and delete operation to not call synchronize_net()
   but to piggy back on SOCK_RCU_FREE for sockets instead as we are not
   allowed to sleep under RCU, from Björn.

2) Do not change RLIMIT_MEMLOCK in reuseport_bpf selftest if the process
   already has unlimited RLIMIT_MEMLOCK, from Eric.

Please consider pulling these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git

Thanks a lot!
