- The sysctl interface provides a means of dynamically changing
- certain kernel parameters and variables on the fly without requiring
- a recompile of the kernel or reboot of the system. The primary
- interface consists of a system call, but if you say Y to "/proc
- file system support", a tree of modifiable sysctl entries will be

+config TASKSTATS
+ bool "Export task/process statistics through netlink (EXPERIMENTAL)"

+ default n
+ help
+ Export selected statistics for tasks/processes through the
+ generic netlink interface. Unlike BSD process accounting, the
+ statistics are available during the lifetime of tasks/processes as
+ responses to commands. Like BSD accounting, they are sent to user
+ space on task exit.
- As it is generally a good thing, you should say Y here unless
- building a kernel for install/rescue disks or your system is very
- limited in memory.
+ Say N if unsure.

+ help
+ Collect information on time spent by a task waiting for system

+ relative to other tasks for cpu, io, rss limits etc.
