  "message": "[PATCH] cpuset: skip rcu check if task is in root cpuset\n\nFor systems that aren\u0027t using cpusets, but have them CONFIG_CPUSET enabled in\ntheir kernel (eventually this may be most distribution kernels), this patch\nremoves even the minimal rcu_read_lock() from the memory page allocation path.\n\nActually, it removes that rcu call for any task that is in the root cpuset\n(top_cpuset), which on systems not actively using cpusets, is all tasks.\n\nWe don\u0027t need the rcu check for tasks in the top_cpuset, because the\ntop_cpuset is statically allocated, so at no risk of being freed out from\nunderneath us.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
