So, I recently attempted to upgrade from Linux kernel 4.19.82 to
5.15.23, and I'm getting a critical error in dmesg about a corrupt
leaf (and no mounting of /home allowed with the options I'm aware of)

Interestingly. that 18446... number is a power of 2, looks like maybe
a bit flip? dmesg, uname, etc included in pastebin below. "btrfs
check" found no problems with fs on either kernel version. Would like
to figure out how to fix this, if possible.

The read time tree checker was added in 4.18 but there were
enhancements in ~5.1 to 5.3. This could be a bug introduced into the
file system from an older kernel.
I'm not sure why btrfs check isn't seeing it. What version of btrfs-progs?
You can recover by copying the affected files out of this file system
to a new one while using a current 4.19 series kernel. It won't hit
the tree checker error. One strategy could be making read-only
snapshots and using btrfs send receive to replicate to a new btrfs
file system, using 4.19 kernel. If you can isolate the problem being
triggered to just a file or a directory - you could copy that
directory to another file system, delete it, and then copy it back.

Please provide the following output:
# btrfs ins dump-tree -b 10442806968320 /dev/sda2
The error message means, we got a DIR_ITEM in root tree.
Normally that is used to indicate what default subvolume is.
Thus it's normally 6 or 5, or any valid subvolume id.
But in your case, it's 1, thus tree-checker is rejecting your root tree.
I didn't thought we could have 1 as default subvolume (as 1 is the root
tree, which is not a subvolume).
But it looks like we should update btrfs check to fix this case.
Is the fs created using older btrfs-progs? I guess that may be the cause...
Thanks,
Qu

This filesystem was most likely created in 2014 using the tools of
that time, at least that's the oldest file in my home directory. It
_might_ have been made in 2019, that's the date on the mount point.
There are 2 subvolumes on /dev/sda2, /home and /var.
My btrfs-progs version is 5.15.1.

Weird, the output doesn't match the dmesg.
This tree belongs to csum tree, not root tree.

Qu,
here's what I got on 5.15.23
dump-tree root /dev/sda2 on kernel 5.15.23 here: https://paste.ee/p/kSdI2
Warning: 2+MB text dump, this is a good-sized, and well-used, fs.
Thank you,
-- Laurence

Exactly what I'm expecting:
item 8 key (ROOT_TREE_DIR DIR_ITEM 2378154706) itemoff 14697 itemsize 37
location key (ROOT_TREE UNKNOWN.0 0) type DIR
transid 0 data_len 0 name_len 7
name: default
Note the location key, it doesn't point to any real subvolume.
Thus newer kernel is rejecting it.
To fix it, you can try the following command using your older working
kernel:
# btrfs subvolume set-default 5 <mount point>
Then try if the newer kernel handles it without problem.
Thanks,
Qu
