+Subject: [PATCH] Fix: net: expose sk wmem in sock_exceed_buf_limit tracepoint
+ (4.19)
+
+See upstream commit:
+
+  commit d6f19938eb031ee2158272757db33258153ae59c
+  Author: Yafang Shao <laoar.shao@gmail.com>

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