## Overview

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

xfs: don't leak new_bp if xfs_btree_bload_drop_buf fails

LOLLM observes that in xfs_btree_bload_prep_block,
xfs_btree_bload_drop_buf can hit an IO error if writing the delwri
buffer list to disk fails.  In this case, we fail to release new_bp,
which means we lose a locked buffer.  Fix that.

## Remediation

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