Subject: [PATCH net-next 0/5] inet_diag: make dumps faster with simple filters

inet_diag_bc_sk() pulls five cache lines per socket,
while most filters only need the two first ones.

We can change it to only pull needed cache lines,
to make things like "ss -temoi src :21456" much faster.

First patches (1-3) are annotating data-races as a first step.

Eric Dumazet (5):
  inet_diag: annotate data-races in inet_diag_msg_common_fill()
  tcp: annotate data-races in tcp_req_diag_fill()
  inet_diag: annotate data-races in inet_diag_bc_sk()
  inet_diag: change inet_diag_bc_sk() first argument
  inet_diag: avoid cache line misses in inet_diag_bc_sk()
