Additionally, some patches were sent related to the caching/flushing(still
pending to get reviewed):
https://patchwork.freedesktop.org/patch/96042/
https://patchwork.freedesktop.org/patch/96041/
https://patchwork.freedesktop.org/patch/96044/
https://patchwork.freedesktop.org/patch/96043/

Just in case you want to test if they help.
