Dominique Martinet 1a4f69ef15 9p/client: fix data race on req->status ... KCSAN reported a race between writing req->status in p9_client_cb and accessing it in p9_client_rpc's wait_event. Accesses to req itself is protected by the data barrier (writing req fields, write barrier, writing status // reading status, read barrier, reading other req fields), but status accesses themselves apparently also must be annotated properly with WRITE_ONCE/READ_ONCE when we access it without locks. Follows: - error paths writing status in various threads all can notify p9_client_rpc, so these all also need WRITE_ONCE - there's a similar read loop in trans_virtio for zc case that also needs READ_ONCE - other reads in trans_fd should be protected by the trans_fd lock and lists state machine, as corresponding writers all are within trans_fd and should be under the same lock. If KCSAN complains on them we likely will have something else to fix as well, so it's better to leave them unmarked and look again if required.
