This introduces two new cases:
- 3 hardlinks without any subvolume
This should results 3 hard links inside the btrfs.
- 3 hardlinks, but a subvolume will split 2 of them
Then the 2 inside the same subvolume should still report 2 nlinks,
but the lone one inside the new subvolume can only report 1 nlink.

Add a new option --subvol, which tells mkfs.btrfs to create the
specified directories as subvolumes when used with --rootdir.
Given a populated directory dir, the command
$ mkfs.btrfs --rootdir dir --subvol usr --subvol home --subvol home/username img
will create subvolumes 'usr' and 'home' within the toplevel subvolume,
and subvolume 'username' within the 'home' subvolume. It will fail if
any of the directories do not yet exist.

There's a report that newly added --rootdir print too many warnings for
hardlinks, which is maybe not that uncommon. We still want to let the
user know about that so print it just once and count how many were
found:
$ mkfs.btrfs --rootdir ...
WARNING: '/tmp/btrfs-progs-mkfs-rootdir-hardlinks.7RcdfR/rootdir/inside_link' has extra hardlinks, they will be converted into new inodes

The new test case creates a special layout like this:
rootdir/ (fs1 ino=256)
|- dir1/ (fs1 ino=257)
| |- dir1/ (fs2 ino=257)
| |- dir2/ (fs2 ino=258)
| |- file1 (fs2 ino=259)
| |- file2 (fs2 ino=260)
|- dir2/ (fs1 ino=258)
|- file1 (fs1 ino=259)
|- file2 (fs2 ino=259)
This layout intentionally creates inode number conflicts, which will
make the old "mkfs.btrfs --rootdir" to fail.
But newer reworked one will successfully handle them, just leave a test
case to avoid to hit the old bugs.

The test case will create the following directory layout:
.
|- rootdir/
| |- inside_link
|- outside_link
Both inside_link and outside_link are hard links of each other.
And use rootdir/ as the rootdir for mkfs.
This is to ensure the nlink of inside_link is correctly set to 1.
Inspired by the recent rework which fixes the handling of hard links.

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 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.

Since a few days the CI started to fail randomly when there were loop
devices used in the tests. The mount fails because some device is
reported to be missing:
$ losetup --show --find
/dev/loop3
...
$ mkfs ...
ERROR: device scan failed on '/dev/loop3': No such file or directory
...
$ mount
mount: /home/runner/work/btrfs-progs/btrfs-progs/tests/mnt: wrong fs
type, bad option, bad superblock on /dev/loop3, missing codepage or
helper program, or other error.
$ dmesg
...
BTRFS error (device loop0): devid 3 uuid 11d9c345-9527-433e-a024-7102659fa0ee is missing
BTRFS error (device loop0): failed to read the system array: -2
BTRFS error (device loop0): open_ctree failed
This was reproducible in the "cli" tests, but also happened on a local
machine.
To fix that wait for all loop devices before mount, the command
'btrfs device ready' should block until that. The convenience helper
does that, for any standalone 'mount' used with loop devices this must
be done manually.
Signed-off-by: David Sterba <dsterba@suse.com>
The new test case would:
- Prepare two loopback devices
One is for storing the source directory (on a btrfs).
This is to ensure we can set xattr for the directory, as filesystems
like tmpfs (mostly utilized by mktemp) is not supporting xattr.
The other one is the real target fs where we call
"mkfs.btrfs --rootdir" on.
- Create the source directory with the following contents:
* rootdir inode attributs:
# mode (750)
# uid (1000)
# gid (1000)
# xattr (user.rootdir)
* one regular file, with attributes:
# xattr (user.foorbar)
- Execute "mkfs.btrfs --rootdir" and mount the new fs
- Verify the above attributes
The target fs should have the same attributes, especially for the
rootdir inode.

During my test runs of mkfs-tests, 005-long-device-name-for-ssd failed

Command failed.

[CAUSE]
There seems to be a race between "btrfs inspect dump-super" and the
dmsetup removal.
[FIX]
Add a "udevadm settle" before removing the dm devices.
Also since we're here, use the same "udevadm settle" instead of the
manual sleep to wait for the new dm device to show up.

Add a runtime feature (-R) flag for the free space tree. A filesystem
that is mkfs'd with -R free-space-tree then mounted with no options has
the same contents as one mkfs'd without the option, then mounted with
'-o space_cache=v2'.
The only tricky thing is in exactly how to call the tree creation code.
Using btrfs_create_free_space_tree as is did not quite work, because an
extra reference to the eb (root->commit_root) is leaked, which mkfs
complains about with a warning. I opted to follow how the uuid tree is
created by adding it to the dirty roots list for cleanup by
commit_tree_roots in commit_transaction. As a result,
btrfs_create_free_space_tree no longer exactly matches the version in
the kernel sources.
