Add a stress test for fs-verity. This tests enabling fs-verity on
multiple files concurrently with concurrent readers on those files
(with reads occurring before, during, and after the fs-verity
enablement), while fsstress is also running on the same filesystem.
I haven't seen any failures from running this on ext4 and f2fs.

The test case checks if btrfs can trim adjacent extents across
adjacent block groups boundary correctly.
The test case craft the following extents layout:
| BG1 | BG2 | BG3 |
Bytenr: X-8M X X+512M X+1G X+1G+128M
|//////|//////| | |//|
There is a long existing bug that, when btrfs is trying to trim the
range at [X+512M, X+1G+128M), it will only trim [X+512M, X+1G).
This test case is the regression test for this long existing bug.
It will verify the trimmed bytes by using loopback device backed up
by a file, and checking the bytes used by the file to determine how
many bytes are trimmed.

Calling src/<file> without path '$here' may cause the problem that
the file cannot be found.
For example, Running generic/192 with overlayfs(Let ubifs as base
fs) yields the following output:
generic/192 - output mismatch
QA output created by 192
sleep for 5 seconds
test
+./common/rc: line 316: src/t_dir_type: No such file or directory
delta1 is in range
delta2 is in range
...
When the use case fails, the call stack in generic/192 is:
local unknowns=$(src/t_dir_type $dir u | wc -l) common/rc
_supports_filetype common/rc
_overlay_mount common/overlay
_overlay_test_mount common/overlay
_test_mount common/rc
_test_cycle_mount generic/192
Before _test_cycle_mount() being invoked, generic/192 executed 'cd
/' to change work dir from 'xfstests-dev' to '/', so src/t_dir_type
was not found.
[Eryu: some tests run src/<file> as regular user, don't add $here
prefix in such case, as a regular user may have no search permission
on $here]

-----------------------------------

It fails because the broken is always equal to 0 when

not. As a result, the test exits and runs the cleanup function
without the $BASE_TEST_FILE variable set and the shell expands it to

Rename-overwrites over NFS work with a "silly rename" over the
network, so the nlink count stays at 1 instead of dropping to 0.
This is expected behavior for NFS, so we should use a different
golden output file to account for this.
See the NFS faq at: nfs.sourceforge.net/#faq_d2 for more
information about silly renames.

The filesystem population code frequently allocates a large file and
punches out every other block ("swiss-cheese files") in an attempt to
cause the creation of a lot of metadata to fill out the btrees. This
pattern, however, has a subtle bug if the writes to the swiss-cheese
file are not allocated in batches and we're trying to fragment the free
space records in order to achieve a certain metadata btree shape.
This is exactly what happens on a DAX filesystem, since we no longer
have the page cache to stage delalloc writes. Each xfs_io pwrite call
to the multi-megabyte swiss-chese file turns into multiple 4k pwrites,
which means that file data blocks are allocated 4k at a time. This can
be fatal to our goal of fragmenting the free space btrees because the
allocator sees a 4k allocation request and uses 4k blocks from the
fragmented parts of the free space to satisfy the "small" request. When
this happens, the XFS populate function cannot fill out the free space
btree to sufficient height and tests fail.
(In regular delalloc mode we'd cache all those small write() in memory
and try for a single large allocation, which we'd generally get.)
To fix this, we need to force the filesystem to allocate all blocks
before freeing any blocks. Split the creation of swiss-cheese files
into two parts: (a) writing data to the file to force allocation, and
(b) punching the holes to fragment free space.
This bug affects only XFS but we convert the one ext4 usage anyway.
