+ help
+ When Y this option provides accounting and allows configuring
+ limits for user's consumption of exhaustible system resources.
+ The most important resource controlled by this patch is unswappable
+ memory (either mlock'ed or used by internal kernel structures and
+ buffers). The main goal of this patch is to protect processes
+ from running short of important resources because of accidental
+ misbehavior of processes or malicious activity aiming to ``kill''
+ the system. It's worth mentioning that resource limits configured
+ by setrlimit(2) do not give an acceptable level of protection
+ because they cover only a small fraction of resources and work on a
+ per-process basis. Per-process accounting doesn't prevent malicious
+ users from spawning a lot of resource-consuming processes.
