Video showing the 4 MB leak in 25 seconds
It was found that the kernel 5.0 has a memory leak when Vulkan applications are
used. It seems this leak can be even more intense than the one from <a class="bz_bug_link

title="CLOSED FIXED - ANV driver doesn't release memory"
href="show_bug.cgi?id=107899">bug 107899</a>.
On drm-tip and linux-git, the commit 61a98b1b9a8c7a21a2d666a090dcf5f1c70c659f
fixes this leak. However, the leak is present on the kernel 5.0.5, currently
the latest stable.
vulkan-smoketest is enough to trigger the leak. On slabtop, it shows:
80275 80275 100% 0,62K 3211 25 51376K i915_request
Steps to reproduce:
1) Open a Vulkan application, for example, vulkan-smoketest.
System information:
OS: Xubuntu 18.04;
Kernel: 5.0.0-8 (Disco Dingo) to 5.0.5;
CPU: Intel Core i3-6100U;
GPU: Intel HD Graphics 520;
Memory: 8 GB.</pre>
