This test case will check the following behviour:
- Regular zoned supported data/metadata profiles
Should success
- RST with zoned feature
Should fail for non-experimental builds
- zoned with data profiles that only RST supports
Should fail for non-experimental builds.
Meanwhile for experimental builds it should success and enable RST
feature automatically (verified in mkfs/030)

Currently raid-stripe-tree feature is still experimental as it requires
a BTRFS_DEBUG kernel to recognize it. To avoid confusion move it back
to experimental so regular users won't incorrectly set it.
And since RST is no longer supported by default, also change the RST
profile detection so that for non-experimental build we won't enable RST
according to the data profiles.

Currently we unconditionally run mkfs/029 and mkfs/030 as we export
RST feature through mkfs.btrfs as supported features.
But considering the mkfs.btrfs features don't match kernel support (only
a BTRFS_DEBUG kernel can support that), we're going to hide RST behind
experimental builds.
In that case RST related tests cases also need to be behind experimental
builds as regular builds of mkfs.btrfs will no longer support RST
feature.
Introduce two helpers:
- _test_config()
To verify if certain config is set to 1
- check_experimental_build()
A wrapper of "_test_config EXPERIMENTAL", and skip the test if
btrfs-progs has no experimental features.
So that test cases can be skipped for non-experimental builds.

The raid-stripe-tree (RST) feature is for zoned devices to support extra
data profiles, and is not yet a stable feature (still requires
CONFIG_BTRFS_DEBUG enabled kernel to support it).
Furthermore the supported filesystems (ext*, reiserfs and ntfs) don't
even support zoned devices, and even we force RST support for
btrfs-convert, we would only create an empty tree for RST, as btrfs
convert would only result SINGLE data profile with SINGLE/DUP metadata
profile, neither needs RST at all.
Enabling RST for btrfs-convert would only cause problems for false test
failures as we incorrectly allow RST feature for btrfs-convert.
Fixes the problem by removing raid-stripe-tree support from
btrfs-convert and remove the test cases support for RST.
This patch is mostly reverting commit 346a381923 ("btrfs-progs:
convert: add raid-stripe-tree to allowed features"), but keeps the test
infrastructure to support bgt features for convert.

[BUG]
There is a random failure for misc/028 in github CI, but unable to
reproduce locally.
[EXTRA DUMP]
The failure is at mount time, which is mostly out of our control (kernel
is provided by the CI image), but at least we can do extra kernel dump
if a mount fails.
This dump is done inside run_check() where if we detects there is a
"mount" word inside the command string.
The detection is not the best, it may detect other commands that
contains the word "mount", but it should be good enough to detect real

[BUG]
There is a random chance that misc/055 would fail with stale qgroups
detected.
[CAUSE]
Commit 82f7d6c1d7 ("btrfs-progs: qgroup: handle stale qgroup deletion
more accurately") changed the behavior of "btrfs qgroup clear-stale"
that it will no longer try to remove qgroup under deletion.
And the test case itself relies on the return value of "btrfs qgroup
clear-stale" to do the extra wait for subvolume deletion.
This means after that commit, the test case would skip the wait if there
is a subvolume waiting for cleanup, resulting in a race window where the
subvolume can be dropped and become stale, and eventually trigger the
stale qgroup detection and cause false alerts.
[FIX]
Fix the test case by always wait for the subvolume to be dropped, so
that later "btrfs qgroup clear-stale" can properly remove all stale
qgroups.

[BUG]
There is a bug report that a canceled checksum conversion (still
experimental feature) resulted in unexpected super flags:
csum_type 0 (crc32c)
csum_size 4
csum 0x14973811 [match]
bytenr 65536
flags 0x1000000001
( WRITTEN |
CHANGING_FSID_V2 )
magic _BHRfS_M [match]
While for a filesystem under checksum conversion it should have either
CHANGING_DATA_CSUM or CHANGING_META_CSUM.
[CAUSE]
It turns out that, due to btrfs-progs keeps its own extra flags inside
its own ctree.h headers, not the shared uapi headers, we have
conflicting super flags:
kernel-shared/uapi/btrfs_tree.h:#define BTRFS_SUPER_FLAG_METADUMP_V2 (1ULL << 34)
kernel-shared/uapi/btrfs_tree.h:#define BTRFS_SUPER_FLAG_CHANGING_FSID (1ULL << 35)
kernel-shared/uapi/btrfs_tree.h:#define BTRFS_SUPER_FLAG_CHANGING_FSID_V2 (1ULL << 36)
kernel-shared/ctree.h:#define BTRFS_SUPER_FLAG_CHANGING_DATA_CSUM (1ULL << 36)
kernel-shared/ctree.h:#define BTRFS_SUPER_FLAG_CHANGING_META_CSUM (1ULL << 37)
Note that CHANGING_FSID_V2 is conflicting with CHANGING_DATA_CSUM.
[FIX]
Cross port the proper updated uapi headers into btrfs-progs, and remove
the definition from ctree.h.
This would change the value for CHANGING_DATA_CSUM and
CHANGING_META_CSUM, but considering they are experimental features, and
kernel would reject them anyway, the damage is not that huge and we can
accept such change before exposing it to end users.

there, resulting no extra space for the convert balance.

The test case verifies behavior of ext4 unwritten extents:
- Create a unwritten (preallocated) extent on ext4
- Fill the on-disk extent with random garbage
This is to make sure if btrfs tries to read the on-disk data, it would
definitely get some garbage.
As I found sometimes mkfs.ext4 can fill the unused bg with zeros.
- Fill the preallocated file range with some data
This is to make sure btrfs-convert can handle mixed written and
unwritten ranges.
- Save the checksum of the file.
- Convert the fs
- Verify the checksum
For older btrfs-convert, there would be only one regular file extent,
and reading the file would read out some garbage and cause checksum to
mismatch.
For the fixed btrfs-convert, we punch holes for unwritten extents,
thus only the written part would be read out and match the checksum.

[BUG]
There is a bug report that btrfs-convert cannot handle unwritten extents
(EXT2_EXTENT_FLAGS_UNINIT set, which is pretty much the same as
BTRFS_FILE_EXTENT_PREALLOC), which can cause the converted image to have
incorrect contents.
[CAUSE]
Currently we use ext2fs_block_iterate2() to go through all data extents
of an ext2 inode, but it doesn't provide the info on if the range is
unwritten or not.
Thus for unwritten extents, the results btrfs would just treat it as
regular extents, and read the contents from disk other than setting the
contents to zero.
[FIX]
Instead of the ext2fs_block_iterate2(), here we follow the debugfs'
"dump_extents" command, to use ext2fs_extent_*() helpers to go through
every data extent of the inode, that's if the inode supports the
EXT4_EXTENTS_FL flag.
Now we can properly get the info of which extents are unwritten, and use
holes to replace those unwritten extents.

Even with "mkfs.btrfs -b", mkfs.btrfs resets all the zones on the device.
Limit the reset target within the specified length.
Also, we need to check that there is no active zone outside of the FS
range. Having an active zone outside FS reduces the number of zones btrfs
can write simultaneously. Technically, we can still scan all the device
zones and keep active zones outside FS intact and try to live with the
limited active zones. But, that will make btrfs operations harder.
It is generally bad idea to use "-b" on a non-test usage on a device with
active zone limit in the first place. You really need to take care that FS
and outside the FS goes over the limit. That means you'll never be able to
use zones outside the FS anyway.
So, until there is a strong request for that, I don't think it's worthwhile

- inclusion of dependency files directive never found them because the
list was not updated to look to .deps, also there were some ancient
files mentioned
- the dependency generation commands were run before each target,
slowing down build
How it works now:
- dependencies are created before each .c file is compiled, so that way
any changes to the file get translated to the dependency files
- missing dependencies are create after first run
- there's single dependency file for all build types (box, static, both)
