The lvm command can invoke the thin pool utilities as part of
managing a thin volume. It'll fail if the thin provisioning
utilities are not installed, so we need to check for its presence
before running a test.

This test case writes into pre-allocated space, then tries to
fallocate some more within the defined quota limit. Currently
(4.14-rc7) this fails with EDQUOT due to quota reservation leakage
when writing into pre- allocated space.
A possible fix has been sent to the ML as "btrfs: Fix quota
reservation leak on preallocated files"

kernel v4.13 introduced the index=on feature for not breaking
hardlinks on copy-up. With the index feature enabled a regression
was introduced - lower files that are hardlined while overlay is
offline can result in lookup error after overlay in mounted.
The regression was fixed by upstream commit
6eaf011144af ovl: fix EIO from lookup of non-indexed upper
that was merged to v4.14-rc7.
This test verifies that behavior is sane after creating lower
hardlinks for copied up files while overlayfs is offline.

In generic/459, if the DISCARD of the thin device somehow fails with
this message:
device-mapper: thin: Data device (dm-1) discard unsupported: Disabling discard passdown.
Then we can end up with arbitrary gunk in the thin device. This
causes mkfs to fail because it's afraid to format the device. Don't
be afraid, just zap it. FWIW mkfs.xfs thinks that the thinp device
has an xfs external log because sometimes the thinp device just
happen to be backed by the log of the previous test's scratch fs.
Fix this by making the _mkfs_dev helper always format the device,
per Eryu Guan's suggestion.

Occasionally speculative preallocation kicks in when writing files
to a filesystem under test. These preallocations consume quota and
/usually/ aren't around after we drop_caches, but there's nothing to
guarantee that they actually have, so the quota reports will be
different before and after the fs remount, causing sporadic test
failures in generic/{23[123],270}.
We now have xfs_spaceman which can instruct XFS to forcibly remove
the speculative preallocations. This fixes the sporadic failures,
at least for XFS.

XFS had a bug that resulted in an unexpected NULL buffer during
unlink of an inode with a multi-level attr fork tree. This occurred
due to a stale reference to content in a released/reclaimed buffer.
Use the XFS buffer LRU reference count error injection tag to
recreate the conditions for the bug. Create a file with a
multi-level attr fork tree and then unlink it with buffer caching
disabled.
Commit f35c5e10c6ed ("xfs: reinit btree pointer on attr tree

This commit adds a test to verify consistent d_ino feature when
the overlayfs instance is composed of two different underlying
filesystem instances.
For example,
$ mount -t xfs /dev/loop0 /mnt/test
$ mount -t xfs /dev/loop1 /mnt/scratch
$ mkdir /mnt/scratch/upper
$ mkdir /mnt/scratch/work
$ mount -t overlay overlay -o lowerdir=/mnt/test \
-o upperdir=/mnt/scratch/upper \
-o workdir=/mnt/scratch/work /mnt/merge
The goal of this test is to verify that the inode numbers returned by
readdir(3) (i.e. dirent->d_ino) are consistent with inode numbers
returned by stat(2) (i.e. stat->st_ino) in all the below listed cases,
- Parent's (i.e. "..") d_ino must always be calculated because a
pure dir can be residing inside a merged dir.
- d_ino for "." must always be calculated because the present
directory can have a copy-up origin.
- Verify d_ino of '.' and '..' before and after dir becomes impure.
While at it also verify if trusted.overlay.impure xattr is
set/reset appropriately and invalidation of readdir cache.
- Verify copied up file's (inside a impure dir) d_ino.
- Verify invalidation of readdir cache.
- Verify d_ino values corresponding to "." and ".." entries of a
pure lower dir.
- Verify d_ino of ".." entry of a merged dir.
- Verify pure lower residing in dir which has another lower layer
