Could it be the issue that has been reported independently by several
users?

E.g.:
https://lore.kernel.org/linux-btrfs/2291416ef48d98059f9fdc5d865b0ff040148237.camel@scientia.org/T/#u

Unfortunately, except for Josef Bacik's reply
(https://lore.kernel.org/all/Y1aeWdHd4%2FluzhAu@localhost.localdomain/)
there hasn't been any further word on this from any btrfs developer, so
it's hard to tell for people whether that issue could have caused any
further corruptions on the affected filesystems.

Also, in my case... I noticed the issue on some mv operation, as well
as on send|receive.... but otherwise I could mount my space cache v1
filesystems just normal without and lockups.
So it's also unclear, why it doesn't always show up.

Cheers,
Chris.
