Tetsuo Handa 360aa72192 net: rds: don't hold sock lock when cancelling work from rds_tcp_reset_callbacks() ... [ Upstream commit a91b750fd6629354460282bbf5146c01b05c4859 ] syzbot is reporting lockdep warning at rds_tcp_reset_callbacks() [1], for commit ac3615e7f3 ("RDS: TCP: Reduce code duplication in rds_tcp_reset_callbacks()") added cancel_delayed_work_sync() into a section protected by lock_sock() without realizing that rds_send_xmit() might call lock_sock(). We don't need to protect cancel_delayed_work_sync() using lock_sock(), for even if rds_{send,recv}_worker() re-queued this work while __flush_work() from cancel_delayed_work_sync() was waiting for this work to complete, retried rds_{send,recv}_worker() is no-op due to the absence of RDS_CONN_UP bit.
