I'm confused. I thought what Eddie was talking about is the case where we
have two initiators (well two sessions). One of them issues some commands.
The other does a LU reset, wiping out those commands. Then the first comes
along and does a task management request on the original commands, which
aren't there anymore because the other session did a reset (and thus the
Task Management command can't work on them).

Or is that not what Eddie was talking about?

Take care,
