Sorry, it took a while for me to get started on it. Anyways, thanks for providing fixes. I applied those and ran some tests on AMD Milan machine:
- Built in perf tests ran fine without any issues - perf_event_tests reported one BUG_ON() and one WARN_ON(). I'll work on fixing those. - Ran perf fuzzer for almost a day. It reported one softlockup but system recovered from it and later it reported one hardlockup but unfortunately my config had HARDLOCKUP_PANIC set and thus couldn't confirm whether that hardlockup was recoverable or not. Anyway, system was running pretty much fine until then. - No lockdep warnings were observed in any of the tests.
I'll work on verifying functionality changes.
Thanks, Ravi
