Subject: [PATCH net-next v6] net/sock: Introduce trace_sk_data_ready()

From: Peilin Ye <peilin.ye@...edance.com>

As suggested by Cong, introduce a tracepoint for all ->sk_data_ready()
callback implementations.  For example:

<...>
  ksoftirqd/0-16  [000] ..s..  99.784482: sk_data_ready: family=10 protocol=58 func=sock_def_readable
  ksoftirqd/0-16  [000] ..s..  99.784819: sk_data_ready: family=10 protocol=58 func=sock_def_readable
<...>

Suggested-by: Cong Wang <cong.wang@...edance.com>
Signed-off-by: Peilin Ye <peilin.ye@...edance.com>
---
v1-v5: https://lore.kernel.org/netdev/20220928221514.27350-1-yepeilin.cs@gmail.com/

change since v5:
  - Rebase onto net-next

change since v4:
  - Add back tracepoint in iscsi_target_sk_data_ready()

changes since v3:
  - Avoid using __func__ everywhere (Leon Romanovsky)
  - Delete tracepoint in iscsi_target_sk_data_ready()

change since v2:
  - Fix modpost error for modules (kernel test robot)

changes since v1:
  - Move tracepoint into ->sk_data_ready() callback implementations
    (Eric Dumazet)
  - Fix W=1 warning (Jakub Kicinski)
