 Flexible Block Groups
 ---------------------
 
 Starting in ext4, there is a new feature called flexible block groups
-(flex\_bg). In a flex\_bg, several block groups are tied together as one
+(flex_bg). In a flex_bg, several block groups are tied together as one
 logical block group; the bitmap spaces and the inode table space in the
-first block group of the flex\_bg are expanded to include the bitmaps

 superblock, group descriptors, data block bitmaps for groups 0-3, inode
 bitmaps for groups 0-3, inode tables for groups 0-3, and the remaining
 space in group 0 is for file data. The effect of this is to group the
 block group metadata close together for faster loading, and to enable
 large files to be continuous on disk. Backup copies of the superblock
 and group descriptors are always at the beginning of block groups, even

+Without the option META_BG, for safety concerns, all block group
 descriptors copies are kept in the first block group. Given the default
 128MiB(2^27 bytes) block group size and 64-byte group descriptors, ext4
 can have at most 2^27/64 = 2^21 block groups. This limits the entire
 filesystem size to 2^21 * 2^27 = 2^48bytes or 256TiB.
 
 The solution to this problem is to use the metablock group feature
-(META\_BG), which is already in ext3 for all 2.6 releases. With the
-META\_BG feature, ext4 filesystems are partitioned into many metablock
+(META_BG), which is already in ext3 for all 2.6 releases. With the

 descriptor structures can be stored in a single disk block. For ext4
