libext2fs: optimize ext2fs_allocate_group_table() By using ext2fs_mark_block_bitmap_range2 and/or ext2fs_block_alloc_stats_range(), we can significantly speed up the time needed by mke2fs to allocate the inode table. For example, the CPU time needed to run the command "mke2fs -t ext4 /tmp/foo.img 32T" (where tmpfs was mounted on /tmp) was decreased from 21.7 CPU seconds down to under 1.7 seconds.
