ERROR: failed to start transaction: Unknown error -28
ERROR: failed to start transaction: No space left on device

ERROR: btrfstune failed
[CAUSE]
After commit e79f18a4a7 ("btrfs-progs: introduce a basic metadata free
space reservation check"), btrfs_start_transaction() would check the
metadata space.
But at the time of introduction of csum conversion, the parameter for
btrfs_start_transaction() was incorrect.
The 2nd parameter is the *number* of items to be added (if we're
deleting items, just pass 1).
However commit 08a3bd7694 ("btrfs-progs: tune: add the ability to
generate new data checksums") is using the item size, not the number of
items to be added.
This means we're passing a number 8 * nodesize times larger than the
original size, no wonder we would error out with -ENOSPC.
[FIX]
Use proper calcuation to convert the new csum item size to number of
leaves needed, and double it just in case.

Enhance the sorting capabilities of 'inspect list-chunks' to allow
multiple keys. Drop the gaps, this works only for pstart and it's hard
to make it work with arbitrary sort keys.
Usage is printed by default, assuming this is an interesting info and
even if it slows down the output (due to extra lookups) it's more
convenient to print it rather than not.
The options related to usage and empty were removed.
Output changes:
- rename Number to PNumber, meaning physical number on the device
- print Devid, device number, can be also sort key
Examples:
btrfs inspect list-chunks /mnt
btrfs inspect list-chunks --sort length,usage
btrfs inspect list-chunks --sort lstart
Depending on the sort key order, the output can be wild, for that the
PNumber and LNumber give some hint where the chunks lie in their space.
Example output:
$ sudo ./btrfs inspect list-chunks --sort length,usage /
Devid PNumber Type/profile PStart Length PEnd LNumber LStart Usage%

Currently we unconditionally run mkfs/029 and mkfs/030 as we export

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:

This dump is done inside run_check() where if we detects there is a

[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.

- 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.
