Subject: [PATCH 0/3] Fix two syzbot corruption bugs in minix filesystem

Syzbot fuzzes /fs by trying to mount and manipulate deliberately
corrupted filesystems. This should not lead to BUG_ONs and WARN_ONs for
easy to detect corruptions. This series adds code to be able to report
such corruptions and fixes two syzbot bugs on this kind.

Jori Koolstra (3):
  Add error handling to minix filesystem for inode corruption detection
  Fix a drop_nlink warning in minix_rmdir
  Fix a drop_nlink warning in minix_rename
