Naohiro Aota a85f05e59b btrfs: zoned: avoid chunk allocation if active block group has enough space ... The current extent allocator tries to allocate a new block group when the existing block groups do not have enough space. On a ZNS device, a new block group means a new active zone. If the number of active zones has already reached the max_active_zones, activating a new zone needs to finish an existing zone, leading to wasting the free space there. So, instead, it should reuse the existing active block groups as much as possible when we can't activate any other zones without sacrificing an already activated block group. While at it, I converted find_free_extent_update_loop() to check the found_extent() case early and made the other conditions simpler.
