4.14-stable review patch. If anyone has any objections, please let me know.
commit 95bcade33a8af38755c9b0636e36a36ad3789fe6 upstream.
It seems 9d4646d14d51 ("locking/qspinlock: Elide back-to-back RELEASE operations with smp_wmb()") is improving the fix. Is it worth to take this also?
If someone could test that this really does help things out, I would be glad to take it :)
thanks,
