## Overview

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

xfs: bail out on bitmap errors in xrep_agfl_fill

LOLLM also points out that the xagb_bitmap_set call in xrep_agfl_fill
can fail, but we don't check the result of xagb_bitmap_walk, so we
silently drop the error and proceed with inconsistent incore data.
That shouldn't be allowed.

## Remediation

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