In EXT4 it seems that both direct/indirect and extent tree based block allocation is used. I used debugfs and it seems that the root inode uses the direct/indirect block allocation. The other files and direcyories used extent based allocation. Do all the EXT4 reserved inode (0 -11) use the direct/indirect allocation scheme? -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
