Subject: selftests: pidfd: pidfd_wait hangs on linux next kernel on all devices
Date: Wed, 23 Sep 2020 19:52:05 +0530 [thread overview]
Message-ID: <CA+G9fYtF44bTzjswt26tOwfEQxrWvcSOROmEtH0HKfGn24QbRQ@mail.gmail.com> (raw)
selftests: pidfd: pidfd_wait hangs on linux next kernel on x86_64,
i386 and arm64 Juno-r2
These devices are using NFS mounted rootfs.
I have tested pidfd testcases independently and all test PASS.
The Hang or exit from test run noticed when run by run_kselftest.sh
pidfd_wait.c:208:wait_nonblock:Expected sys_waitid(P_PIDFD, pidfd,
&info, WSTOPPED, NULL) (-1) == 0 (0)
wait_nonblock: Test terminated by assertion
