When updating the global block reserve, we account for the 6 items needed by an unlink operation and the 6 delayed references for each one of those items. However the calculation for the delayed references is not correct in case we have the free space tree enabled, as in that case we need to touch the free space tree as well and therefore need twice the number of bytes. So use the btrfs_calc_delayed_ref_bytes() helper to calculate the number of bytes need for the delayed references at btrfs_update_global_block_rsv(). Reviewed-by:
