When attempting to checkpoint a container with CUDA processes, CRIU could fail with the following error: Error (criu/cr-dump.c:1791): Timeout reached. Try to interrupt: 1 Error (cuda_plugin.c:143): cuda_plugin: Unable to read output of cuda-checkpoint: Interrupted system call Error (cuda_plugin.c:384): cuda_plugin: PAUSE_DEVICES failed with In this situation, the target process is locked, but CRIU fails due to a timeout and exits with an error. We need to make sure that the target PID is unlocked in such case. Signed-off-by: Radostin Stoyanov <rstoyanov@fedoraproject.org>
