The nodes_allowed mask is derived as follows:\n\n* For \"default\" [NULL] task mempolicy, a NULL nodemask_t pointer\n is produced. This will cause the hugetlb subsystem to use\n node_online_map as the \"nodes_allowed\". This preserves the\n behavior before this patch.\n* For \"preferred\" mempolicy, including explicit local allocation,\n a nodemask with the single preferred node will be produced.\n \"local\" policy will NOT track any internode migrations of the\n task adjusting nr_hugepages.\n* For \"bind\" and \"interleave\" policy, the mempolicy\u0027s nodemask\n will be used.\n* Other than to inform the construction of the nodes_allowed node\n mask, the actual mempolicy mode is ignored. That is, all modes\n behave like interleave over the resulting nodes_allowed mask\n with no \"fallback\".\n\nSee the updated documentation [next patch] for more information\nabout the implications of this patch.\n\nExamples:\n\nStarting with:\n\n\tNode 0 HugePages_Total: 0\n\tNode 1 HugePages_Total: 0\n\tNode 2 HugePages_Total: 0\n\tNode 3 HugePages_Total: 0\n\nDefault behavior [with or without this patch] balances persistent\nhugepage allocation across nodes [with sufficient contiguous memory]:\n\n\tsysctl vm.nr_hugepages[_mempolicy]\u003d32\n\nyields:\n\n\tNode 0 HugePages_Total: 8\n\tNode 1 HugePages_Total: 8\n\tNode 2 HugePages_Total: 8\n\tNode 3 HugePages_Total: 8\n\nOf course, we only have nr_hugepages_mempolicy with the patch,\nbut with default mempolicy, nr_hugepages_mempolicy behaves the\nsame as nr_hugepages.\n\nApplying mempolicy--e.g., with numactl [using \u0027-m\u0027 a.k.a.\n\u0027--membind\u0027 because it allows multiple nodes to be specified\nand it\u0027s easy to type]--we can allocate huge pages on\nindividual nodes or sets of nodes.

This causes a problem with the\nfunction_graph tracer because it consumes the iteration in order to\ndetermine leaf functions.\n\nWhat happens is that the iterator stores the entry, and the function\ngraph plugin will look at the next entry. If that next entry is a return\nof the same function and task, then the function is a leaf and the\nfunction_graph plugin calls ring_buffer_read which moves the ring buffer\niterator forward (the trace iterator still points to the function start\nentry).\n\nThe copying of the trace_seq to the seq_file buffer will fail if the\nseq_file buffer is full. The seq_read will not show this entry.\nThe next read by userspace will cause seq_read to again call s_start\nwhich will reuse the trace iterator entry (the function start entry).\nBut the function return entry was already consumed. The function graph\nplugin will think that this entry is a nested function and not a leaf.\n\nTo solve this, the trace code now checks the return status of the\nseq_printf (trace_print_seq). If the writing to the seq_file buffer\nfails, we set a flag in the iterator (leftover) and we do not reset\nthe trace_seq buffer.
