Fairly trivial test to use the dm-thin infrastructure.
Right now it exhausts space in queue-on-error mode,
adds more space, does a bit more IO, then unmounts &
checks the fs.
Not sure if that's valid to test, but it works here and
demonstrates the common/dmthin helpers.

Although the test waits for running subshells after sending SIGTERM
signal to them, it does not wait for subprocesses of those subshells
properly. Thus we can hit EBUSY errors when umount is called. Make
subshells wait for executed subprocesses when receiving SIGTERM to avoid
the problem.

Currently holetest program uses both posix_fallocate(3) and fallocate(3)
to setup the file. However this unnecessarily prolongs the test run and
doesn't really bring any additional code coverage. So remove the
fallocate(3) pass as using posix_fallocate(3) allows us to make the test
easily runnable even for filesystems not supporting that (such as ext2).

Test that an invalid parent qgroup does not cause snapshot create to
force the FS readonly.
In btrfs, create_pending_snapshot() will go readonly on _any_ error return
from
btrfs_qgroup_inherit(). If qgroups are enabled, a user can crash their fs by
just making a snapshot and asking it to inherit from an invalid qgroup.
This patch does exactly that test. If the FS goes readonly that will be
reported and we will know that a regression was introduced.
The btrfs fix this patch relates to can be found at the following url:

Currently xfs/259 tests against TEST_DIR for CRC support status to
decide whether 512 block size should be tested, which is wrong for this
test, because configuration of TEST_DIR is not controlled by test
harness and can be different to the configuration being used in the
test.
Fix it by reversing the block size order that's tested and capture the
output of the actual mkfs command that is being tested, and determine if
512 byte block sizes should be tested based on that output.
While we're at it, I think the test matrix can be enlarged as well, 4k,
2k, 1k and 512 block size can be tested in each fs size boundary, not
only the minimum block size.

The space occupied by files in the 'origin' directory is calculated with
the assumption that 4k is the block size of the underlying filesystem.
This causes the test to fail with ENOSPC errors when running on
filesystems with larger block sizes. To fix the issue, this commit makes
use of the the block size obtained from the mounted filesystem.

Commit 31f48569c3 ("xfs/030: fix output on newer filesystems") added
more lines to .out file to match the output from XFS with reflink
support, but it broke test on older XFS.
Dave explained the reason and pointed out the correct way to fix it, so
I just quote Dave's mail here:
"The problem here is that reflink triggers a change in the initial
population of the AGFL - from 4 blocks to 6 blocks, and so repair warns
6 times instead of 4. After filtering, that gives 6 indentical output
lines instead of 4.
Doing something as simple as collapsing repeated identical lines (e.g
filtering through uniq) will work for all filesystem formats and any
future changes that modify the initial AGFL population."
