Subject: [PATCH v4 1/2] Make a message on process termination more dscriptive
Date: Fri, 24 Dec 2021 12:52:07 +0900
The message at process termination due to slot limit doesn't provide
the reason. In the major scenario the message is followed by another
message about slot invalidatation, which shows the detail for the
termination. However the second message is missing if the slot is
temporary one.
Augment the first message with the reason same as the second message.
Backpatch through to 13 where the message was introduced.
