Hi David, hi Jakub, hi Paolo, hi Eric, The following pull-request contains BPF updates for your *net* tree. We've added 12 non-merge commits during the last 2 day(s) which contain a total of 13 files changed, 190 insertions(+), 91 deletions(-). The main changes are: 1) Fix bpf_xdp_adjust_tail() in context of XSK zero-copy drivers which support XDP multi-buffer. The former triggered a NULL pointer dereference upon shrinking, from Maciej Fijalkowski & Tirthendu Sarkar. 2) Fix a bug in riscv64 BPF JIT which emitted a wrong prologue and epilogue for struct_ops programs, from Pu Lehui.
