>From 8519ca72db9093d80d9a32c4482483c9ef8c51f0 Mon Sep 17 00:00:00 2001 From: Bram Hooimeijer <[email protected]> Date: Thu, 10 Jun 2021 17:27:57 +0200 Subject: [PATCH V3 1/1] inmates/lib: Set cell-state to shutdown in stop()
Ensures that calls to stop(), defined in the inmate library, set the cell-state to shutdown if the cell is still running. This prevents the cell to be locked but unable to respond due to being stuck in the halt() loop. It also ensures that a return to inmate_main() shuts down the cell.
