Hi, I have created an img file and mounted it with ext4 file system. I want to store its information in sb_info str of ext4 file system ext4.h header file. actually i am trying to separately store metadata and the data.For doing that i have created an img file and formatted this partition with ext4. I need to store this partitions information in the ext4_sb_info struct.I am not sure about how to modify the code as i am new to this file system. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
