From f44fa79b104b56d53d33ae43e69bab98b63d4783 Mon Sep 17 00:00:00 2001 From: Vasily Gorbik Date: Fri, 22 Nov 2019 17:37:50 +0100 Subject: s390/test_unwind: require that unwinding ended successfully Currently unwinder test passes if unwinding results contain unwindme_func2 and unwindme_func1 functions. Now that unwinder reports success upon reaching task pt_regs, check that unwinding ended successfully in every test.
