Dani Liberman c37803388c habanalabs: handle race in driver fini ... Scenario: 1. During hard reset, driver executes device_kill_open_processes. 2. Drivers file descriptor is not closed yet (user process is alive), hence we are starting loop on all open file descriptors. 3. Just before getting task struct of user process, according to pid, SIGKILL is sent to the user process, hence get_pid_task fails, driver prints a warning and device_kill_open_processes returns an error. 4. Returned error causing driver fini do disable the device object of the process which causes a kernel crash. The fix is to handle this case not as an error and continue fini flow as normal, since the killed process (by the SIGKILL) will release its resources just like it will do when the driver sends him the sigkill.
