Hi all, this series adds two tests for removing a device underneath the file system. This covers the new shutdown handling series I'm posting. Changes since v2: - don't look for specific logical/physical block sizes on SCRATCH_DEV - use run_check (Zorro Lang) - use SCSI_DEBUG_MNT instead of SCRATCH_DEV (Zorro Lang) Changes since v1: - renumbered the tests - add a check that the tests are only run on block based file systems
