9Description: Weight configuration interface for nodeN
10
11 The interleave weight for a memory node (N). These weights are
12 utilized by tasks which have set their mempolicy to
13 MPOL_WEIGHTED_INTERLEAVE.
14
15 These weights only affect new allocations, and changes at runtime
16 will not cause migrations on already allocated pages.
17
18 The minimum weight for a node is always 1.
19
20 Minimum weight: 1
21 Maximum weight: 255
22
23 Writing an empty string or `0` will reset the weight to the
24 system default. The system default may be set by the kernel
25 or drivers at boot or during hotplug events.
