Subject: [RFC Patch V1 14/30] mm, i40evf: Use cpu_to_mem()/numa_mem_id() to support memoryless node
Date: Fri, 11 Jul 2014 15:37:31 +0800 [thread overview]
Message-ID: <1405064267-11678-15-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1405064267-11678-1-git-send-email-jiang.liu@linux.intel.com>
When CONFIG_HAVE_MEMORYLESS_NODES is enabled, cpu_to_node()/numa_node_id()
may return a node without memory, and later cause system failure/panic
when calling kmalloc_node() and friends with returned node id.
So use cpu_to_mem()/numa_mem_id() instead to get the nearest node with
memory for the/current cpu.
If CONFIG_HAVE_MEMORYLESS_NODES is disabled, cpu_to_mem()/numa_mem_id()
is the same as cpu_to_node()/numa_node_id().
