[Qemu-devel] [PATCH v3 1/5] qemu-iotests: set TEST_DIR to a unique dir for each test

[Jeff Cody <jcody@redhat.com>]

Right now, all qemu-iotests output data into the same scratch directory,
and so each test needs to be responsible for cleaning up its own files.

Have each test use 'scratch/$seq' as its temp directory, so the check
script can do simple cleanup of removing the whole temporary directory.
