dm-flakey can be used to emulate IO write error, however, when we
also need to prevent the IO error for a specific range of the block
device (eg., the log region of a XFS), we need to specify multiple
dm targets for the dm device.
Option --table can not accommodate the multiple dm targets case, so
let dmsetup get the possible-multiple-targets table from standard
input.

Modify _require_odirect() to skip O_DIRECT tests if the ext4 mount
option data=journal has been applied. Because ext4 disables its
O_DIRECT support when in data journaling mode, no significant value
is obtained by running these tests and they consume a significant
amount of run time. Additionally, this change eliminates the need
to triage false negative O_DIRECT test results caused by test
problems, as has occurred from time to time.

Currently generic shutdown tests are enabled on overlayfs by
extending _require_scratch_shutdown() to check shutdown support for
overlayfs, some of those tests also call
_require_metadata_journaling() to inspect whether test filesystem
support metadata journaling or not, so need to extend
_require_metadata_journaling() as well to check metadata journaling
support for overlayfs in case shutdown tests run on uncommon
overlayfs setup and fail. For example, base filesystem of overlayfs
is ext2 or ext4 with noload mode.
Metadata journaling check is based on base filesystem configurations
and because -overlay option saves those configurations to
OVL_BASE_*, adding restore/override the configurations before/after
the check.
Tested ext2, xfs, ext4(load/no-load mode) as base filesystem of
overlayfs in single and multi section configurations.

In this test we use a fixed sequence of operations in fsstress to
create some number of files and dirs and then exercise
xfsdump/xfsrestore on them. Since clonerange/deduperange are not
supported on all xfs configurations, detect if they're in fsstress
and disable them so that we always execute exactly the same sequence
of operations no matter how the filesystem is configured.

Test log recovery with repeated (simulated) disk failures. We kick
off fsstress on the scratch fs, then switch out the underlying
device with dm-error to see what happens when the disk goes down.
Having taken down the fs in this manner, remount it and repeat.
This test is a Good Enough (tm) simulation of our internal multipath

Test case generic/399 hardcodes "-O encrypt" in MKFS_OPTIONS when
calling _scratch_mkfs_sized, which only works with the mkfs of
certain filesystems. Create a new helper,
_scratch_mkfs_sized_encrypted, for handling the differences between
the mkfs tools of different filesystems. It also allows those
filesystems whose mkfs doesn't accept "-O encrypt" to skip the test
gracefully until proper support is added for them in the helper.
ubifs is not supported in the new helper despite supporting
encryption, as _scratch_mkfs_sized has no ubifs support and adding
that should be done in a separate patch.

Enable shutdown tests on overlayfs. This requires configuring
overlayfs with TEST|SCRATCH_DEV pointing to block device, which act
as base fs of overlay. The legacy config (pointing TEST|SCRATCH_DEV
to existing directories) won't support shutdown.
Extend _require_scratch_shutdown() to deal with overlay by checking
shutdown support on $OVL_BASE_SCRATCH_MNT instead of $SCRATCH_MNT,
so we check shutdown support status against the underlying upper fs
of overlay.
Introduce new _scratch_shutdown() helper to do the actual shutdown
work and shutdown upper fs in the case of overlay. Also converting
existing bare 'src/godown' calls to use this helper to avoid false
failures when testing overlayfs.
generic/042 and generic/050 assume $SCRATCH_DEV to be a local
device, so add _require_local_device $SCRATCH_DEV rule.

We're removing from XFS the ability to perform no-allocation file
creation. This was added years ago because some customer of SGI
demanded that we still be able to create (empty?) files with zero
free blocks remaining so long as there were free inodes and space in
existing directory blocks. This came at an unacceptable risk of
ENOSPC'ing midway through a transaction and shutting down the fs, so
we're removing it for the create case having changed our minds 20
years later.
However, some tests fail as a result, so fix them to be more
flexible about not failing when a dir/file creation fails due to
ENOSPC.
