[GIT PULL 11/17 for v6.19] minix

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

/* Summary */
Fix two syzbot corruption bugs in the minix filesystem. Syzbot fuzzes
filesystems by trying to mount and manipulate deliberately corrupted
images. This should not lead to BUG_ONs and WARN_ONs for easy to detect
corruptions.

- Add error handling to minix filesystem for inode corruption detection,
  enabling the filesystem to report such corruptions cleanly.

- Fix a drop_nlink warning in minix_rmdir() triggered by corrupted
  directory link counts.

- Fix a drop_nlink warning in minix_rename() triggered by corrupted
  inode link counts.

/* Testing */

gcc (Debian 14.2.0-19) 14.2.0
Debian clang version 19.1.7 (3+b1)

No build failures or warnings were observed.
