[PATCH 0/3] bcachefs: Fix some hard link count issues

From: Youling Tang <[email protected]>

- Improves error reporting by returning the semantically correct
  -EMLINK error code.
- Fixes the maximum link count validation logic during hard link
  creation.
- Consolidates link count checks at the VFS layer for better
  maintainability.

NOTE: Patch3 alone can resolve this series of issues, but patches1-2
are retained to better trace the problem origins.

Youling Tang (3):
  bcachefs: return -EMLINK instead of -EINVAL when hard link count
    exceeds limit
  bcachefs: Fix maximum link count check when creating hard links
  bcachefs: Move the link counting check to the VFS layer
