When TEST/SCRATCH_DEV are configured to the base fs block device, use this information to mount base fs before running tests, unmount it after running tests and cycle on _test_cycle_mount along with the overlay mounts. This helps catching overlayfs bugs related to leaking objects in underlying (base) fs. To preserve expected tests behavior, the semantics are: - _scratch_mkfs mounts the base fs, cleans all files, creates lower/upper dirs and keeps base fs mounted - _scratch_mount mounts base fs (if needed) and mounts overlay - _scratch_unmount unmounts overlay and base fs Tests that use _scratch_unmount to unmount a custom overlay mount and expect to have access to overlay base dir, were fixed to use explicit umount $SCRATCH_MNT instead. The overlay test itself, does not support formatting the base fs, so config options like MKFS_OPTIONS and FSCK_OPTIONS are ignored on 'check -overlay'. The config option MOUNT_OPTIONS is used to mount the base scratch fs. The config option TEST_FS_MOUNT_OPTS is used to mount the base test fs. The config option OVERLAY_MOUNT_OPTIONS is used to mount both test and scratch overlay mounts.
