Revision 8632385022f2b05a6ca0b9e0f95575865de0e2ce authored by Eric Dumazet on 06 December 2017, 19:08:19 UTC, committed by David S. Miller on 07 December 2017, 19:31:03 UTC
When I switched rcv_rtt_est to high resolution timestamps, I forgot
that tp->tcp_mstamp needed to be refreshed in tcp_rcv_space_adjust()
Using an old timestamp leads to autotuning lags.
Fixes: 645f4c6f2ebd ("tcp: switch rcv_rtt_est and rcvq_space to high resolution timestamps")
