The branch can be fetched from the following git repo:
https://github.com/adam900710/linux/tree/tree_checker_enhance
It's based on v4.18-rc1, with 3 patches already merged into misc-next.
This patchset introduced the following enhanced validation check:
1) chunk/block group/dev extent cross check
Unlike extent tree, such cross check can be implemented pretty easy
with minimal mount time impact.
Now the kernel could do chunk/bg/dev extent check as good as btrfs
check.
2) Locking test to avoid possible deadlock due to extent tree corruption
Unfortunately, for extent tree we can't do really much cross check.
Instead we use the selftest from btrfs_tree_lock() to detect and
avoid deadlock caused by corrupted extent tree.
The 3rd patch "btrfs: Remove unused function btrfs_account_dev_extents_size()"
has also been merged into misc-next.
changelog:
v2:
Added reviewed-by tags from Gu and Nikolay.
Address comment from David for the 4th patch

btrfs: Verify every chunk has corresponding block group at mount time
btrfs: Remove unused function btrfs_account_dev_extents_size()
btrfs: Introduce mount time chunk <-> dev extent mapping check
btrfs: Exit gracefully when failed to add chunk map
btrfs: locking: Allow btrfs_tree_lock() to return error to avoid
deadlock
