In addition to testing xfs_repair on inodes with malformed mode, and fstat of those inodes on a mounted fs, try to also list content of mock directory and readlink of mock symlink. Readdir of mock directory triggers XFS assertion on umount: XFS: Assertion failed: !rwsem_is_locked(&inode->i_rwsem), file: /home/amir/build/src/linux/fs/xfs/xfs_super.c, line: 951 To reproduce, need to comment out the variable 'safety'.
