Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/xe/client: fix deadlock in show_meminfo()<br />
<br />
There is a real deadlock as well as sleeping in atomic() bug in here, if<br />
the bo put happens to be the last ref, since bo destruction wants to<br />
grab the same spinlock and sleeping locks. Fix that by dropping the ref<br />
using xe_bo_put_deferred(), and moving the final commit outside of the<br />
lock. Dropping the lock around the put is tricky since the bo can go<br />
out of scope and delete itself from the list, making it difficult to<br />
navigate to the next list entry.<br />
<br />
(cherry picked from commit 0083b8e6f11d7662283a267d4ce7c966812ffd8a)
