[libcxx-commits] [libcxx] [libc++][z/OS] XFAIL thread_create_failure.pass.cpp on z/OS (PR #147520)

[Zibi Sarbinowski via libcxx-commits]

https://github.com/zibi2 created https://github.com/llvm/llvm-project/pull/147520

Number of threads on z/OS are controlled at the system level and thus we need to XFAIL this test.
