[PATCH] cpu_exclusive sched domains on partial nodes temp fix
This keeps the kernel/cpuset.c routine update_cpu_domains() from invoking the sched.c routine partition_sched_domains() if the cpuset in question doesn't fall on node boundaries. I have boot tested this on an SN2, and with the help of a couple of ad hoc printk's, determined that it does indeed avoid calling the partition_sched_domains() routine on partial nodes. I did not directly verify that this avoids setting up bogus sched domains or avoids the oops that Hawkes saw. This patch imposes a silent artificial constraint on which cpusets can be used to define dynamic sched domains. This patch should allow proceeding with this new feature in 2.6.13 for the configurations in which it is useful (node alligned sched domains) while avoiding trying to setup sched domains in the less useful cases that can cause the kernel corruption and oops.
