## Overview

In the Linux kernel, the following vulnerability has been resolved:

ceph: fix deadlock or deadcode of misusing dget()

The lock order is incorrect between denty and its parent, we should
always make sure that the parent get the lock first.

But since this deadcode is never used and the parent dir will always
be set from the callers, let's just remove it.

## Affected

- `linux_kernel < 4.19.307`
- `linux_kernel >= 4.20, < 5.4.269`
- `linux_kernel >= 5.5, < 5.10.210`
- `linux_kernel >= 5.11, < 5.15.149`
- `linux_kernel >= 5.16, < 6.1.77`
- `linux_kernel >= 6.2, < 6.6.16`
- `linux_kernel >= 6.7, < 6.7.4`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.4`
