rcu/nocb: Use separate flag to indicate disabled ->cblist NULLing the RCU_NEXT_TAIL pointer was a clever way to save a byte, but forward-progress considerations would require that this pointer be both NULL and non-NULL, which, absent a quantum-computer port of the Linux kernel, simply won't happen. This commit therefore creates as separate ->enabled flag to replace the current NULL checks. Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com>
