Ryan, Thanks for the bug submission. The upstream changes are a group of changes that alter the parallelism and concurrency (P&C) of the loader handling of thread local storage. These changes are very new in upstream. I would like to see these changes achieve more operational hours upstream, we already found a defect in the changes that required subsequent fixes (DTV gap reuse logic). P&C issues require millions of CPU hours to make sure we don't see any issues across hardware architectures. I will review these changes as part of our RHEL 8.6.0 planning (estimated release early in 2022).
