This patch add an extra test for passing invalid flags and check its expected failure. It shows an invalid LO_HI_LONG macro definition for x86_64 with leads to passing invalid flags on some configurations. The new tests fails on i686-linux-gnu and potentially on other 32 bits architecture that uses the compat syscall definition due a kernel bug. It is intended to be fixed upstream. Checked on x86_64-linux-gnu * misc/tst-preadvwritev2-common.c: New file. * misc/tst-preadvwritev2.c (do_test): Add test for invalid flag. * misc/tst-preadvwritev64v2.c (do_test): Likewise.
