Kuniyuki IwashimaandGreg Kroah-Hartman 9b8dfaea5c net: Call trace_sock_exceed_buf_limit() for memcg failure with SK_MEM_RECV. ...

[ Upstream commit 9d85c565a7 ]

Initially, trace_sock_exceed_buf_limit() was invoked when
__sk_mem_raise_allocated() failed due to the memcg limit or the
global limit.

However, commit d6f19938eb ("net: expose sk wmem in
sock_exceed_buf_limit tracepoint") somehow suppressed the event
only when memcg failed to charge for SK_MEM_RECV, although the
memcg failure for SK_MEM_SEND still triggers the event.

Let's restore the event for SK_MEM_RECV.
