2006-10-01[PATCH] csa accounting taskstats updateJay Lan1-11/+14
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>
2006-10-01[PATCH] csa: convert CONFIG tag for extended accounting routinesJay Lan1-0/+30
There were a few accounting data/macros that are used in CSA but are #ifdef'ed inside CONFIG_BSD_PROCESS_ACCT. This patch is to change those ifdef's from CONFIG_BSD_PROCESS_ACCT to CONFIG_TASK_XACCT. A few defines are moved from kernel/acct.c and include/linux/acct.h to kernel/tsacct.c and include/linux/tsacct_kern.h.

2006-10-01[PATCH] csa: basic accounting over taskstatsJay Lan1-0/+72
Add some basic accounting fields to the taskstats struct, add a new kernel/tsacct.c to handle basic accounting data handling upon exit. A handle is added to taskstats.c to invoke the basic accounting data handling.
