## Overview

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

f2fs: initialize locks earlier in f2fs_fill_super()

syzbot is reporting lockdep warning at f2fs_handle_error() [1], for
spin_lock(&sbi->error_lock) is called before spin_lock_init() is called.
For safe locking in error handling, move initialization of locks (and
obvious structures) in f2fs_fill_super() to immediately after memory
allocation.

## Affected

- `linux_kernel < 6.1.11`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.1.11`
