3.8.13.14-rt31-rc1 stable review patch. If anyone has any objections, please let me know. ------------------ From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> Since it is no longer invoked from the softirq people run into OOM more often if the priority of the RCU thread is too low. Making boosting default on RT should help in those case and it can be switched off if someone knows better.
