Hello:

This patch was applied to netdev/net-next.git (main)

rs_seen_congestion is read in rds_poll() and written in rds_sendmsg()
and rds_poll() without any lock.  Use READ_ONCE()/WRITE_ONCE() to
annotate these lockless accesses and silence KCSAN.

Fixes: b98ba52f96e7 ("RDS: only put sockets that have seen congestion on the poll_waitq")
