Tang Chen 8f28ed92d9 Documentation/vm/numa_memory_policy.txt: fix wrong document in numa_memory_policy.txt
In document numa_memory_policy.txt, the following examples for flag
MPOL_F_RELATIVE_NODES are incorrect.

	For example, consider a task that is attached to a cpuset with
	mems 2-5 that sets an Interleave policy over the same set with
	MPOL_F_RELATIVE_NODES.  If the cpuset's mems change to 3-7, the
	interleave now occurs over nodes 3,5-6.  If the cpuset's mems
	then change to 0,2-3,5, then the interleave occurs over nodes
	0,3,5.

According to the comment of the patch adding flag MPOL_F_RELATIVE_NODES,
the nodemasks the user specifies should be considered relative to the
current task's mems_allowed.

 (https://lkml.org/lkml/2008/2/29/428)

And according to numa_memory_policy.txt, if the user's nodemask includes
nodes that are outside the range of the new set of allowed nodes, then
the remap wraps around to the beginning of the nodemask and, if not
already set, sets the node in the mempolicy nodemask.

So in the example, if the user specifies 2-5, for a task whose
mems_allowed is 3-7, the nodemasks should be remapped the third, fourth,
fifth, sixth node in mems_allowed.  like the following:

	mems_allowed:       3  4  5  6  7

	relative index:     0  1  2  3  4
	                    5

So the nodemasks should be remapped to 3,5-7, but not 3,5-6.

And for a task whose mems_allowed is 0,2-3,5, the nodemasks should be
remapped to 0,2-3,5, but not 0,3,5.

	mems_allowed:       0  2  3  5

        relative index:     0  1  2  3
                            4  5
