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.

1. The global stack named MOUNTED_POINT_STACK
2. _get_mount() accepts mount parameters like _mount() does, but the

4. _clear_mount_stack() doesn't need any parameter either. It will

xfs: fuzz every field of every structure

Previously, our XFS fuzzing efforts were limited to using the xfs_db
blocktrash command to scribble garbage all over a block.  This is
pretty easy to discover; it would be far more interesting if we could
fuzz individual fields looking for unhandled corner cases.  Since we
now have an online scrub tool, use it to check for our targeted
corruptions prior to the usual steps of writing to the FS, taking it
offline, repairing, and re-checking.

These tests use the new xfs_db 'fuzz' command to test corner case
handling of every field.  The 'print' command tells us which fields
are available, and the fuzz command can write zeroes or ones to the
field; set the high, middle, or low bit; add or subtract numbers; or
randomize the field.  We loop through all fields and all fuzz verbs to
see if we can trip up the kernel.
