This patch is to offer common accounting data collection method at memory usage for various accounting packages including BSD accounting, ELSA, CSA and any other acct packages that use a common layer of data collection. New struct fields are added to mm_struct to save high watermarks of rss usage as well as virtual memory usage. New struct fields are added to task_struct to collect accumulated rss usage and vm usages. These data are collected on per process basis.
