Do you know about !mex.ctbsar?

This command says that you can sort process to a desired value, but no matter how hard you try, you can’t find help with the !ctbsar command.
Does anyone know how to use it?
(What do tableid and columnid mean?)

0: kd> !mex.ctbsar

No idea, but what are you trying to do?

In order to find hang processes, I wanted to sort the processes by the item waitTime.

I should use !mex.tasklist instead of using !mex.ctbsar first.

anyway, thanks.
