17 Memory policies should not be confused with cpusets
20 memory may be allocated by a set of processes. Memory policies are a
22 both cpusets and policies are applied to a task, the restrictions of the cpuset
63 In a multi-threaded task, task policies apply only to the thread
90 VMA policies have a few complicating details:
102 * VMA policies are shared between all tasks that share a
105 fork(). However, because VMA policies refer to a specific
107 space is discarded and recreated on exec*(), VMA policies
109 applications may use VMA policies.
125 Conceptually, shared policies apply to "memory objects" mapped
127 application installs shared policies the same way as VMA
128 policies--using the mbind() system call specifying a range of
130 VMA policies, which can be considered to be an attribute of a
131 range of a task's address space, shared policies apply
145 As mentioned above in :ref:`VMA policies <vma_policy>` section,
153 The shared policy infrastructure supports different policies on subset
171 Internally, memory policies are implemented by a reference counted
276 MPOL_PREFERRED policies that were created with an empty nodemask
317 nodemasks to specify memory policies using this flag should

366 target task's task policy nor vma policies because we always acquire the
369 installing or replacing task or vma policies. Thus, there is no possibility
378 4) Shared policies require special consideration. One task can replace a
385 extra reference on shared policies in the same query/allocation paths
386 used for non-shared policies. For this reason, shared policies are marked
388 for shared policies.
391 shared policies in a tree structure under spinlock, shared policies are
393 true for shared policies on shared memory regions shared by tasks running
477 Memory policies work within cpusets as described above. For memory policies
487 The interaction of memory policies and cpusets can be problematic when tasks
491 memories are allowed in both cpusets may be used in the policies. Obtaining
