Test case for mkfs to handle if total device size overflows 16EiB. The
device images are created inside temporary btrfs so this works on any

It's theoretically possible to add multiple devices with sizes that add up
to or exceed 16EiB. A file system will be created successfully but will
have a superblock with incorrect values for total_bytes and other fields.
Kernels up to v5.0 will crash when they encounter this scenario.
We need to check for overflow and reject the device if it would overflow.

This patch addes the ability to report and repair root generation in

Notes on test:
- Don't use grep -q, as it causes a SIGPIPE during the countdown, and

When creating a filesystem with mixed block groups, we are creating two
space info objects to track used/reserved/pinned space, one only for data
and another one only for metadata.
This is making fstests test case generic/416 fail, with btrfs' check
reporting over an hundred errors about bad extents:
(...)
bad extent [17186816, 17190912), type mismatch with chunk
bad extent [17195008, 17199104), type mismatch with chunk
bad extent [17203200, 17207296), type mismatch with chunk
(...)
Because, surprisingly, this results in block groups that do not have the
BTRFS_BLOCK_GROUP_DATA flag set but have data extents allocated in them.
This is a regression introduced in btrfs-progs v5.2.
So fix this by making sure we only create one space info object, for both
metadata and data, when mixed block groups are enabled.

While testing snapshot deletion with dm-log-writes I saw that I was
failing the fsck sometimes when the fs was actually in the correct
state. This is because we only skip blocks on the same level of
root_item->drop_level. If the drop_level < the root level then we could
very well walk into nodes that we wouldn't actually walk into on fs
mount, because the drop_progress is further ahead in the slot of the
root. Instead only process the slots of the nodes that are above the
drop_progress key. With this patch in place we no longer improperly
fail to check fs'es that have a drop_progress set with a drop_level <
root level.

[BUG]
Btrfs-progs sometimes fails to find certain extent backref when
committing transaction.
The most reliable way to reproduce it is fsck-test/013 on 64K page sized
system:
[...]
adding new data backref on 315859712 root 287 owner 292 offset 0 found 1
btrfs unable to find ref byte nr 31850496 parent 0 root 2 owner 0 offset 0
Failed to find [30867456, 168, 65536]
Also there are some github bug reports related to this problem.
[CAUSE]
Commit 909357e867 ("btrfs-progs: Wire up delayed refs") introduced
delayed refs in btrfs-progs.
However in that commit, delayed refs are not run at correct timing.
That commit calls btrfs_run_delayed_refs() before
btrfs_write_dirty_block_groups(), which needs to update
BLOCK_GROUP_ITEMs in extent tree, thus could cause new delayed refs.
This means each time we commit a transaction, we may screw up the extent
tree by dropping some pending delayed refs, like:
Transaction 711:
btrfs_commit_transaction()
|- btrfs_run_delayed_refs()
| Now all delayed refs are written to extent tree
|
|- btrfs_write_dirty_block_groups()
| Needs to update extent tree root
| ADD_DELAYED_REF to 315859712.
| Delayed refs are attached to current trans handle.
|
|- __commit_transaction()
|- write_ctree_super()
|- btrfs_finish_extent_commit()
|- kfree(trans)
Now delayed ref for 315859712 are lost
Transaction 712:
Tree block 315859712 get dropped
btrfs_commit_transaction()
|- btrfs_run_delayed_refs()
|- run_one_delayed_ref()
|- __free_extent()
As previous ADD_DELAYED_REF to 315859712 is lost, extent tree
doesn't have any backref for 315859712, causing the bug
In fact, commit c31edf610c ("btrfs-progs: Fix false ENOSPC alert by
tracking used space correctly") detects the tree block leakage, but in
the reproducer we have too much noise, thus nobody notices the leakage
warning.
[FIX]
We can't just move btrfs_run_delayed_refs() after
btrfs_write_dirty_block_groups(), as during btrfs_run_delayed_refs(), we
can re-dirty block groups.
Thus we need to exhaust both delayed refs and dirty blocks.
This patch will call btrfs_write_dirty_block_groups() and
btrfs_run_delayed_refs() in a loop until both delayed refs and dirty
blocks are exhausted. Much like what we do in commit_cowonly_roots() in
kernel.
Also, to prevent such problem from happening again (and not to debug
such problem again), add extra check on delayed refs before freeing the
transaction handle.

The test cli-tests/008-subvolume-get-set-default fails when compiled

misaligned address 0x7ffc147e4b6f for type 'const struct
btrfs_ioctl_search_header', which requires 8 byte alignment
Note that using the accessors does not fix the ubsan warning, as it
warns on taking the address of a member whose _base_ type is unaligned,
ie. it's the 'sh'.
Fixing that would need to play tricks with pointers to do &sh->type
manually, but to avoid triggering ubsan.
