EXT4 internal format question


Can both EXT4_FEATURE_INCOMPAT_META_BG and EXT4_FEATURE_INCOMPAT_FLEX_BG flags turn on the same time? If yes, I am wondering whether there is a correlation between the numbers of block groups in META group and FLEX group. Where are backups of superblock and group description table (GDT) stored in this case?
