Currently, the "foreach DE ps -m" command may display "DE" as well as
"ZO" state tasks as below:
crash> foreach DE ps -m
...
[0 00:00:00.040] [ZO] PID: 11458 TASK: ffff91c75680d280 CPU: 7 COMMAND: "ora_w01o_p01mci"
[0 00:00:00.044] [ZO] PID: 49118 TASK: ffff91c7bf3e8000 CPU: 19 COMMAND: "oracle_49118_p0"
[0 00:00:00.050] [ZO] PID: 28748 TASK: ffff91a7cbde3180 CPU: 2 COMMAND: "ora_imr0_p01sci"
[0 00:00:00.050] [DE] PID: 28405 TASK: ffff91a7c8eb0000 CPU: 27 COMMAND: "ora_vktm_p01sci"
[0 00:00:00.051] [ZO] PID: 31716 TASK: ffff91a7f7192100 CPU: 6 COMMAND: "ora_p001_p01sci"
...
That is not expected behavior, the "foreach" command needs to handle
such cases. Let's add a check to determine if the task state identifier
is specified and the task state identifier is equal to the "DE", so that
it can filter out the non-"DE" state tasks.
With the patch:
crash> foreach DE ps -m
[0 00:00:00.050] [DE] PID: 28405 TASK: ffff91a7c8eb0000 CPU: 27 COMMAND: "ora_vktm_p01sci"
crash>
