[LTP] Remove pidns14 test case

[LTP] Remove pidns14 test case

[M. Mohan Kumar]

[PATCH] Remove pidns14 test case
Container-init may be immune to unhandled fatal signals (like SIGUSR1)
even if they are from ancestor namespace. SIGKILL/SIGSTOP are the only
reliable signals to a container-init from ancestor namespace. So remove
test case pidns14 from container test suite. Please check git commit id
b3bfa0cba867f23365b81658b47efd906830879b for the kernel changes.

Re: [LTP] Remove pidns14 test case

[M. Mohan Kumar]

Hi Subrata,

July LTP release has partially removed pidns14 test case. Still the
runpidnstest.sh script has reference to pidns14 test case. My patch removed
all of the references. Could you please remove the reference to pidns14 in
runpidnstest.sh script also?

Regards,
M. Mohan Kumar.
