Well, I assume we may have 3 fields here:
u8 version;
u8 compat_fset;
u8 incompat_fset;
u8 rocompat_fset;
+ jint32_t erase_count; /* the erase count of this erase block */
4 bytes enough?
+ jint16_t dsize; /* the size of additional data behind node_crc */
What for?
+ jint32_t node_crc;
+ jint32_t data_crc;
+ jint32_t data[0];
