Hello, Ingo, This series adds a small change to yesterday's pull request, namely changing the default value of the srcutree.exp_holdoff kernel boot parameter from 50 microseconds to 25 microseconds. This change completely eliminates the performance shortfall that Mike Galbraith observed. This commit is available in the git repository at:
