Can I have a couple of volunteers review the changes to remove the scan
only prefix code? The changes can be found at
In particular pay close attention to the changes in
G1CollectorPolicy::calculate_young_list_target_config) where the code
that calculates the length of the young list (the innermost loop) had to
be separated from the code that varied the size of the so-prefix.
Testing: refworkload, SPECjbb2005 (with fixed and variable sized young
generation size). I also enabled the tracing the young list config code
and compared the output from a reference workspace.
