The problem about core dump

[AaronDot]

Hi,
I find some test cases, such as kill11 and mmap16, that will produce the core dump in the system.
But these test cases are still passed at last.
Is this normal?
How can I explain it?

This is a kernel testsuite some test are crashing on purpose since we need to (ideally) cover all codepaths in the kernel.

And we could also add tst_no_corefile(0) in the target process to avoid dumping core file if possible.

i.e like what we do for testcases/kernel/syscalls/pkeys/pkey01.c
https://github.com/linux-test-project/ltp/blob/master/include/tst_coredump.h

OK，I see.
I will have a try!

Thanks.
