In some circumstances, when a Red Hat Enterprise Linux client connected to a re-booted Windows-based NFS server, server-side filehandle-to-inode mapping changes caused a kernel panic. "bad_inode_ops" handling was changed to prevent this.
Note: filehandle-to-inode mapping changes may still cause errors, but not panics.
