sysctl_vm_numa_stat_handler | |
min_free_kbytes_sysctl_handler | min_free_kbytes_sysctl_handler - just a wrapper around proc_dointvec() so* that we can call two helper functions whenever min_free_kbytes* changes. |

lowmem_reserve_ratio_sysctl_handler | lowmem_reserve_ratio_sysctl_handler - just a wrapper around* proc_dointvec() so that we can call setup_per_zone_lowmem_reserve()* whenever sysctl_lowmem_reserve_ratio changes.* The reserve ratio obviously has absolutely no relation with the |
percpu_pagelist_fraction_sysctl_handler | percpu_pagelist_fraction - changes the pcp->high for each zone on each* cpu. It is the fraction of total pages in each zone that a hot per cpu* pagelist can have before it gets flushed back to buddy allocator. |
