>Description:

If the command (comm field) is included in ps output and is the last field,
both the process and thread names are displayed separated by a slash.  If
however it is not the last field, only the process name is shown.

[emaste at ref8-amd64 ~]$ ps -axH -o pid,lwp,comm | head
  PID    LWP COMMAND
    0 100000 kernel/swapper
    0 100025 kernel/thread taskq
    0 100028 kernel/acpi_task_0
[...]

[emaste at ref8-amd64 ~]$ ps -axH -o comm,pid,lwp | head
COMMAND               PID    LWP
kernel                  0 100000
kernel                  0 100025
kernel                  0 100028
[...]

>How-To-Repeat:
Run ps with comm as a -o flag and not the last column.
