## Overview

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

gfs2: move quota_init qc iterator increment

Move qc++ from the loop body into the for-loop increment
expression in gfs2_quota_init().

This keeps iterator progression explicit and avoids mixing pointer
advance with duplicate-slot handling in the loop body.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
