Hi,
I was transferring some data with rsync to a btrfs filesystem when I got:

There is a drawback in that defragmentation re-dups data that is previously
deduped or shared in snapshots/subvolumes.

Dear experts,
At first reaction to just switching autodefrag on was positive, but
mentions of re-duplication are very scary. Main use of BTRFS here is
backup snapshots, so re-duplication would be disastrous.
In order to stick to concrete example, let there be two files, 4KB and
4GB in size,

Alright I just reworked the build tree ref stuff and tested it to make sure it
wasn’t going to give false positives again. Apparently I had only ever used
this with very basic existing fs’es and nothing super complicated, so it was
just broken for anything complex. I’ve pushed it to my tree, y

What's the error? Is it ENOSPC? Kinda needs kernel messages, and also
if it's ENOSPC to have mounted with enospc_debug option.
In btrfs_fsck_reinit_root, when btrfs_alloc_free_block fail, it will
update on original root.
Before update it, used btrfs_mark_buffer_dirty to set the flag to EXTENT_DIRTY.
So, we should call clean_tree_block to clear the flag if update fail.

The following test failed becasuse there is no data/metadata/system block_group.
Use return ret to replace BUG_ON(ret) to avoid system crash, because there is
enough message for user to understand what happened.

I'm running Arch Linux on BTRFS. I use Snapper to take hourly
