Thanks for such a detailed explanation.
Now I think we can continue to try to complete the idea[1] from
Kirill Tkhai. The patch moves heavy synchronize_srcu() to delayed
work, so it doesn't affect on user-visible unregistration speed.

A blast from the past! ;-)
But yes, moving the long-latency synchronize_srcu() off the user-visible
critical code path can be even better.
Yeah, I applied these patches ([PATCH RFC 04/10]~[PATCH RFC 10/10],
with few conflicts), the ops/s does get back to the previous levels.
I'll continue updating this patchset after doing more testing.
Thanks,
Qi
Thanx, Paul
