| |
Hello, Ingo,
The single commit in this pull request fixes a regression spotted by Sergey Senozhatsky (https://lkml.org/lkml/2012/4/2/34). The underlying problem is that some CPU_DYING notifiers post RCU callbacks from a CPU that has been marked offline. The long-term fix is to adopt those callbacks from RCU's CPU_DEAD notifier in the 3.5 release. For 3.4, this commit simply shuts off the warning. (Yes, the warning will return in 3.5 also.)
This change is available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/urgent
Thanx, Paul
