## Overview

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

block: integrity: Do not call set_page_dirty_lock()

Placing multiple protection information buffers inside the same page
can lead to oopses because set_page_dirty_lock() can't be called from
interrupt context.

Since a protection information buffer is not backed by a file there is
no point in setting its page dirty, there is nothing to synchronize.
Drop the call to set_page_dirty_lock() and remove the last argument to
bio_integrity_unpin_bvec().

## Affected

- `Linux >= 492c5d455969fc2e829f26ed4c83487b068f0dd7 < c38a005e6efb9ddfa06bd8353b82379d6fd5d6c4`
- `Linux >= 492c5d455969fc2e829f26ed4c83487b068f0dd7 < 9487fc1a10b3aa89feb24e7cedeccaaf63074617`
- `Linux >= 492c5d455969fc2e829f26ed4c83487b068f0dd7 < 39e160505198ff8c158f11bce2ba19809a756e8b`
- `Linux 6.8`
