There are two commits in this series: 1. Minimal patch that #ifdefs out the kthread code. 2. Code-movement patch that puts the code #ifdefed out above under existing #ifdefs in kernel/rcutree_plugin.h. These changes are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/urgent Thanx, Paul ------------------> Paul E.
