Subject: [PATCH net-next v2 0/5] tcp_cubic: various fixes

This patch series converts tcp_cubic to usec clock resolution
for Hystart logic.

This makes Hystart more relevant for data-center flows.
Prior to this series, Hystart was not kicking, or was
kicking without good reason, since the 1ms clock was too coarse.

Last patch also fixes an issue with Hystart vs TCP pacing.

v2: removed a last-minute debug chunk from last patch

Eric Dumazet (5):
  tcp_cubic: optimize hystart_update()
  tcp_cubic: remove one conditional from hystart_update()
  tcp_cubic: switch bictcp_clock() to usec resolution
  tcp_cubic: tweak Hystart detection for short RTT flows
  tcp_cubic: make Hystart aware of pacing
