Hi, list: I find size of struct ext4_inode is 152 bytes, but from the dumpe2fs, it tells me the inode size is 128 bytes. I am confused that, the ext4_inode is the on-disk inode format, so how can dumpe2fs tells the inode size is 128 bytes. Further more, when I use sb_bread() to read inode from inode table (with 152 bytes inode size), I can not read proper data from the bh->b_data. Once I use 128 bytes inode size, I can read what I want from the bh->b_data. I believe there is something I missed, can anybody give me some points ? Thanks in advance.
