X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f54b3278164405fdd4f5f1b53f0d04e34ade27a6;p=linux.git selftests/resctrl: Kill child process before parent process terminates if SIGTERM is received In kselftest framework, a sub test is run using the timeout utility and it will send SIGTERM to the test upon timeout. In resctrl_tests, a child process is created by fork() to run benchmark but SIGTERM is not set in sigaction(). If SIGTERM signal is received, the parent process will be killed, but the child process still exists. Kill child process before the parent process terminates if SIGTERM signal is received.
