## Overview

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

f2fs: fix to avoid potential panic during recovery

During recovery, if FAULT_BLOCK is on, it is possible that
f2fs_reserve_new_block() will return -ENOSPC during recovery,
then it may trigger panic.

Also, if fault injection rate is 1 and only FAULT_BLOCK fault
type is on, it may encounter deadloop in loop of block reservation.

Let's change as below to fix these issues:
- remove bug_on() to avoid panic.
- limit the loop count of block reservation to avoid potential
deadloop.

## Affected

- `linux_kernel >= 4.19.307, < 4.20`
- `linux_kernel >= 5.4.269, < 5.5`
- `linux_kernel >= 5.10.210, < 5.11`
- `linux_kernel >= 5.15.149, < 5.16`
- `linux_kernel >= 6.1.77, < 6.1.83`
- `linux_kernel >= 6.6.16, < 6.6.23`
- `linux_kernel >= 6.7.4, < 6.7.11`
- `linux_kernel >= 6.8, < 6.8.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.2`
