Merge patch series "Fix two syzbot corruption bugs in minix filesystem"
Jori Koolstra <jkoolstra@xs4all.nl> says:
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.
* patches from https://patch.msgid.link/20251104143005.3283980-1-jkoolstra@xs4all.nl:
Fix a drop_nlink warning in minix_rename
Fix a drop_nlink warning in minix_rmdir
Add error handling to minix filesystem for inode corruption detection
