Shin'ichiro Kawasaki 7da1afa444 btrfs: zoned: set pseudo max append zone limit in zone emulation mode ... commit cac5c44c48 upstream. The commit 7d7672bc5d ("btrfs: convert count_max_extents() to use fs_info->max_extent_size") introduced a division by fs_info->max_extent_size. This max_extent_size is initialized with max zone append limit size of the device btrfs runs on. However, in zone emulation mode, the device is not zoned then its zone append limit is zero. This resulted in zero value of fs_info->max_extent_size and caused zero division error. Fix the error by setting non-zero pseudo value to max append zone limit in zone emulation mode. Set the pseudo value based on max_segments as suggested in the commit c2ae7b772e ("btrfs: zoned: revive max_zone_append_bytes").
