Hi,

Im using your fair scheduler patch (2.4.19-fairsched),
applied on top of 2.4.20-rmap15a+read_latency2, and
everything seems great. However, I have one small
doubt, ps output seems a little strange, some
processes appear to be out of order. To illustrate,
here's the output of ps. Im wondering, is this normal?

bash-2.0.5b# ps -eo pid,ppid,user,command
  PID PPID USER COMMAND
    3 1 root [ksoftirqd_CPU0]
    2 1 root [keventd]
    5 1 root [kscand]
    6 1 root [bdflush]
    8 1 root [kreiserfsd]
  410 1 root /sbin/dhcpcd eth0
  551 1 root [eth1]
  613 1 root klogd -x
  627 1 root sshd
    1 0 root init [3]
  682 627 root sshd
  685 684 kurt -bash
  760 685 root su -
  799 1 root xinetd
  604 1 root syslogd -m 0
  820 1 snmp /usr/sbin/snmpd
  841 1 root logger -t safe_mysqld
  840 1 root /bin/sh /usr/bin/safe_mysqld
  870 840 mysql /usr/sbin/mysqld
    4 1 root [kswapd]
  894 885 httpd /usr/sbin/httpd -DSSL
  893 885 httpd /usr/sbin/httpd -DSSL
  885 1 root /usr/sbin/httpd -DSSL
  898 885 httpd /usr/sbin/httpd -DSSL
  680 1 root portsentry -audp
  681 1 root portsentry -atcp
  665 1 root crond
    7 1 root [kupdated]
  761 760 root -bash
  684 682 kurt sshd
 1003 761 root ps -eo pid,ppid,user,command

Without the fairsched patch, ps output is normal, eg,
init is always the first process listed, all kernel
threads appear at the top (notice kswapd and kupdated
near the bottom), and processes with lower pids never
appear after others with higher (eg, portsentry is 680
and was started before httpd which is 898, yet it
still appears after it). Im just wondering, is this
purely aesthetically or is there something fishy?

Regards,

//kj
