Subject: [linux-next:master] [lockref]  d042dae6ad:  unixbench.throughput
 -33.7% regression



Hello,

kernel test robot noticed a -33.7% regression of unixbench.throughput on:


commit: d042dae6ad74df8a00ee8a3c6b77b53bc9e32f64 ("lockref: speculatively spin waiting for the lock to be released")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master

testcase: unixbench
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:

	runtime: 300s
	nr_task: 100%
	test: shell1
	cpufreq_governor: performance


In addition to that, the commit also has significant impact on the following tests:
