7 | The /sys/kernel/slab directory contains a snapshot of the | ||
8 | internal state of the SLUB allocator for each cache. Certain | ||
9 | files may be modified to change the behavior of the cache (and | ||
10 | any cache it aliases, if any). | ||

397 | The file remote_node_defrag_ratio specifies the percentage of | ||
398 | times SLUB will attempt to refill the cpu slab with a partial | ||
399 | slab from a remote node as opposed to allocating a new slab on | ||
