函数名称: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

函数原型:int lowmem_reserve_ratio_sysctl_handler(struct ctl_table *table, int write, void __user *buffer, size_t *length, loff_t *ppos)

7974  setup_per_zone_lowmem_reserve - called whenever* sysctl_lowmem_reserve_ratio changes. Ensures that each zone* has a correct pages reserved value, so an adequate number of* pages are left in the zone after a successful __alloc_pages().
