How was "120" chosen for CONFIG_DEFAULT_HUNG_TASK_TIMEOUT?

[Mailing Lists]

Hello,

I'm trying to understand how this value has been chosen.
Was it arbitrary, or did it come up after some rationale?

If alter it to a lower value like 30 (or 60), and a piece of third
party code hung in D state triggers the kernel hung task complain
message, can I still report this as an issue to that code's issue
tracker even if the message is not shown at default value of 120?

Thanks.
