Hi Greg,
this patch doesn't need any backporting to stable. The failure can only happen on v5.16-rcX.
Really? The Fixes: tag says otherwise: Fixes: c2707a255623 ("btrfs: zoned: add a dedicated data relocation block group") as that commit id is in 5.15.4.
Perhaps that tag is incorrect?
Nope, but 5.15.4 does not contain the functions where we forgot to add the calls to btrfs_clear_data_reloc_bg().
The bug was a race between me and Naohiro working on c2707a255623 and afba2bc036b0e ("btrfs: zoned: implement active zone tracking").
Thanks, Johannes
