The original bug fix patch applied cleanly except for files os_linux.cpp and os_posix.cpp. But, the resulting hand merge resulted in code very similar to the original fix. After applying the patch to a JDK-16u repo and modifying the appropriate os_<..>.cpp files, the fix was regression tested by running Mach5 tiers 1 and 2 on Linux, Windows, and Mac OS, and running tiers 3-5 on Linux x64.

Looks like an accurate backport.

Thanks,
David
