QXL indeed unrefs pinned BOs and the warnings are spamming peoples log files.
Make sure we warn only once until the QXL driver is fixed.

Can you pls add FIXME comments to each that qxl is broken and needs to be fixed first? Also please add a References: link to the bug report on lore.kernel.org or wherever it was.
Was there a bug report? I only got notifications by mail so far.
Well that's how bug reports work in the wider kernel community. You need to fish out the right link from mail archives and link to those.
Yes it's not great, but it's imo better to reference these bug reports than have nothing at all. -Daniel
