nptl/tst-eintr1.c test question

[Steve Ellcey <sellcey at cavium dot com>]

I was wondering if anyone else is having problems with nptl/tst-eintr1?
This test is known to fail on some kernels and there is a comment about
it on the glibc wiki.

https://sourceware.org/glibc/wiki/Testing/Testsuite#Known_testsuite_failures

The problem I have is that when this test fails for me on my aarch64 box
it doesn't just result in a failed test, it aborts the whole 'make check'
process and I don't get any results printed out.  I was wondering if there
was some way to make this test not run on some platforms (and how I might
identify what those platforms were).

Maybe something like:

#define BAD_KERNEL (defined (__ARM_ARCH_8A))
#if BAD_KERNEL
static int do_fail (void) { return 1; }
# define TEST_FUNCTION do_fail ()
#else
# define TEST_FUNCTION do_test ()
#endif

I don't know if this test fails on all aarch8/8A platforms, I just know
that it fails for me, so I am not sure what a good way to set BAD_KERNEL
would be.

Any thoughts?

FYI: The failure I get is due to to many forks causing the make process(es) to
abort:
