• b663a79c1   taskstats: add context-switch counters ... Browse Code »

  Make available to the user the following task and process performance
  statistics:

  * Involuntary Context Switches (task_struct->nivcsw)
  * Voluntary Context Switches (task_struct->nvcsw)

  Statistics information is available from:
  1. taskstats interface (Documentation/accounting/)
  2. /proc/PID/status (task only).

  This data is useful for detecting hyperactivity patterns between processes.

• db5fed26b   [PATCH] csa accounting taskstats update ... Browse Code »

  ChangeLog:
  Feedbacks from Andrew Morton:
  - define TS_COMM_LEN to 32
  - change acct_stimexpd field of task_struct to be of
  cputime_t, which is to be used to save the tsk->stime
  of last timer interrupt update.
  - a new Documentation/accounting/taskstats-struct.txt
  to describe fields of taskstats struct.

  Feedback from Balbir Singh:
  - keep the stime of a task to be zero when both stime
  and utime are zero as recoreded in task_struct.

  Misc:
  - convert accumulated RSS/VM from platform dependent
  pages-ticks to MBytes-usecs in the kernel
