To maximize the utilization of inode space, we introduced the inline
tail feature. This feature modifies the inode structure, requiring
support from the f2fs tools.
The inode layout /w inline tail:
| inode block | 4096 | inline tail enable |
| --------------- | ---- | --------------------------|
| inode info | 360 | |
| --------------- | ---- | --------------------------|
| | | extra info | 0~36 |
| | | **compact_addr[16] | 64 |
| addr table[923] | 3692 | reserved | 4 |
| | | **tail data | |
| | | inline_xattr | 200 |
| --------------- | ---- | --------------------------|
| nid table[5] | 20 |
| node footer | 24 |
