[PATCH] csa accounting taskstats update 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 Cc: Shailabh Nagar <nagar@watson.ibm.com> Cc: Balbir Singh <balbir@in.ibm.com> Cc: Jes Sorensen <jes@sgi.com> Cc: Chris Sturtivant <csturtiv@sgi.com> Cc: Tony Ernst <tee@sgi.com> Cc: Guillaume Thouvenin <guillaume.thouvenin@bull.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

taskstats: add context-switch counters 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.
