[Qemu-devel] [PATCH v4 4/7] iotests: Valgrind fails with nonexistent directory

[Andrey Shinkevich <andrey.shinkevich@virtuozzo.com>]

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 and notify the user of it.
