Next: [PATCH RFC tip/core/rcu 13/16] rcu: print boot-time console messages if RCU configs out of ordinary
From: Paul E. McKenney on 15 Apr 2010 14:20
The CPU_STALL_VERBOSE kernel configuration parameter was added to
2.6.34 to identify any preempted/blocked tasks that were preventing
the current grace period from completing when running preemptible
RCU. As is conventional for new configurations parameters, this
defaulted disabled. It is now time to enable it by default.
