13 net: expose sk wmem in sock_exceed_buf_limit tracepoint
14
15 Currently trace_sock_exceed_buf_limit() only show rmem info,
16 but wmem limit may also be hit.
17 So expose wmem info in this tracepoint as well.
18
19 Regarding memcg, I think it is better to introduce a new tracepoint(if
20 that is needed), i.e. trace_memcg_limit_hit other than show memcg info in
21 trace_sock_exceed_buf_limit.
