BTW, your patch series lacks performance data to justify the addition of
quite a lot of complexity to the core locking code. We are unlikely to
take this without sufficient justification.
In the cover letter, these is performance test result for AMD EPYC
7551 and
Zhaoxin KH40000. I listed the perf epoll, locktorture mutex, unixbench
and fxmark.
What test do you think is important for the Lock performance?
I will do more test in next submission.
Ah, I was not sent to/cc on the cover-letter. I only got your patches
1-4. Yes, you did sent out a cover letter with some performance numbers
after checking the LKML list. I will take a closer look at these
performance numbers later as I am attending the LPC conference this week.
