common/rc: add scratch shutdown support for overlayfs
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.

xfs: fix tests to handle removal of no-alloc create nonfeature

btrfs: make sure btrfs can handle full fs trim correctly
Ancient commit f4c697e6406d ("btrfs: return EINVAL if start >
total_bytes in fitrim ioctl") introduced a regression where btrfs
may fail to trim any free space in existing block groups.
It's caused by confusion with btrfs_super_block->total_bytes and
btrfs logical address space.
Unlike physical address, any aligned bytenr in range [0, U64_MAX) is
valid in btrfs logical address space, and it's chunk mapping
mechanism of btrfs to handle the logical<->physical mapping.
The test case will craft a btrfs with the following features:
0) Single data/meta profile
Make trimmed bytes reporting and chunk allocation more predictable.
1) All chunks start beyond super_block->total_bytes (1G)
By relocating these blocks several times.
2) Unallocated space is less than 50% of the whole fs
3) Fragmented data chunks
Data chunks will be full of fragments, 50% of data chunks will be
free space.
So in theory fstrim should be able to trim over 50% space of the fs.
(after fix, 64% of the fs can be trimmed)
While the regression makes btrfs only able to trim unallocated
space, which is less than 50% of the total space.
(without fix, it's only 31%)
Fixed by patch named "btrfs: Ensure btrfs_trim_fs can trim the whole
fs".

kernel v4.13 introduced the index=on feature for not breaking

common/rc: force mkfs for xfs in _mkfs_dev
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.

overlay: Test consistent d_ino feature for non-samefs setup
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
