FWIW, if folks are looking for testcases there are a small number in glibc, a quick grep shows: nptl/tst-cancel20.c nptl/tst-cancel21.c nptl/tst-signal6.c debug/tst-longjmp_chk2.c LTP probably has a bunch too. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
