Run "make run_tests" under strace and send me the output.
Could you share the exact command, how to 'Run "make run_tests" under strace'
strace make run_tests > strace.out 2>&1
Send me strace.out
Thank you for the strace output. kselftest uses a timeout to terminate hung tests - that timeout is 45 seconds. When you run "make run_tests" under watchdog directory, you are running into this.
Yes your fix to add SIGTERM handling makes sense. Please also handle other signals - SIGKILL, SIGQUIT.
Thanks for the find.
thanks, -- Shuah
