From: Paul E. McKenney on 22 Feb 2010 20:50 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. b/kernel/rcutree.c | 2 + b/kernel/rcutree.h | 1 b/kernel/rcutree_plugin.h | 4 --- b/lib/Kconfig.debug | 13 ++++++++++- kernel/rcutree.c | 4 +++ kernel/rcutree_plugin.h | 52 ++++++++++++++++++++++++++++++++++++++++++++++ 6 files changed, 71 insertions(+), 5 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
