## Overview

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

xfs: fix unit conversions in per_binval computation

LOLLM noticed that we're doing the unit conversion in the per_binval
computation backwards -- xfs_buf_inval_log_space's second parameter is
supposed to be in bytes, but max_binval is in units of fsblocks.  Hence
the conversion should be FSB -> B, not the other way around.

## Remediation

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