I think that this shouldn't be a problem. The write is:
conn->peer->last_tx_at = ktime_get_seconds();
and the read is:
keepalive_at = peer->last_tx_at + RXRPC_KEEPALIVE_TIME;
an approximate time is fine as we're estimating when to send a keepalive
packet if we haven't transmitted a packet in a while.
