Tao Ma 0acdb8876f ext4: don't call update_backups() multiple times for the same bg ... When performing an online resize, we add a bunch of groups at one time in ext4_flex_group_add, so in most cases a lot of group descriptors will be in the same group block. But in the end of this function, update_backups will be called for every group descriptor and the same block will be copied and journalled again and again. It is really a waste. Fix things so we only update a particular bg descriptor block once and skip subsequent updates of the same block.
