Official description

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.
