Walkthrough

Reordered imports in three ext4 modules, added an extra_inode_data property and extended Inode checksum to include extra tail bytes when present, added root inode validation in the test with try/except reporting, and bumped project version from 1.2.1 to 1.2.2.

Changes

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Inspect extra_inode_data property behavior and boundary checks in ext4/inode.py.
• Verify checksum inclusion logic for tail bytes and formatting of crc32c usage.
• Confirm test.py catches the correct exception type and that prints/side effects are intentional.
• Quick lint check for import reorderings in ext4/extent.py and ext4/xattr.py.

Poem

🐇 I hopped through bytes both new and old,
Added tails of data, brave and bold,
Imports tidied, tests now check the root,
Version bumped — a gentle, happy toot!
