You mean like this at the start of the script? [ "$VALGRIND_QEMU" == "y" ] && _notrun "valgrind needs a working TMPDIR" I agree that silently doing something different that the user requested is bad and visibly skipping the test is often better. On the other hand, 051 is relatively long and it's only one subtest that doesn't work with valgrind. Hm... How about we do run the test, but put a note in the casenotrun file so it's visible that we didn't use valgrind for everything? Kevin

The Valgrind uses the exported variable TMPDIR and fails if the directory does not exist. Let us exclude such a test case from being run under the Valgrind. Signed-off-by: Andrey Shinkevich <andrey.shinkevich@virtuozzo.com> --- tests/qemu-iotests/051 | 1 + 1 file changed, 1 insertion(+)
