Eric Dumazet 0870b0d8b3 net: busy-poll: use ktime_get_ns() instead of local_clock() ... Typically, busy-polling durations are below 100 usec. When/if the busy-poller thread migrates to another cpu, local_clock() can be off by +/-2msec or more for small values of HZ, depending on the platform. Use ktimer_get_ns() to ensure deterministic behavior, which is the whole point of busy-polling. Fixes: 0602129286 ("net: add low latency socket poll") Fixes: 9a3c71aa80 ("net: convert low latency sockets to sched_clock()") Fixes: 3708983452 ("sched, net: Fixup busy_loop_us_clock()") Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Mina Almasry <almasrymina@google.com> Cc: Willem de Bruijn <willemb@google.com> Reviewed-by: Joe Damato <jdamato@fastly.com> Link: https://patch.msgid.link/20240827114916.223377-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2024-08-28 17:53:13 -07:00
