| |
Hello!
This set backports a couple of RCU CPU stall detection patches from the earlier series (http://lkml.org/lkml/2010/2/22/384) to 2.6.33-rc8 to help track down some NMI issues.
These two patches fix an embarrassing deadlock that can affect TREE_PREEMPT_RCU and add additional per-task output when tasks stall the RCU grace period.
