Comment 1 Chris Wilson 2012-11-22 08:27:43 UTC
An intentional side-effect of the test as it creates obscene numbers of buffers to fill all memory. As it runs as root, it is unaffected by those limits, but any other program try to run in parallel is.
Comment 2 Yi Sun 2012-11-22 09:14:17 UTC
Is it possible to disappear such info since it's not a actual issue, or change its level to 7 in dmesg? As we understood, anything in the dmesg which is high than level 6 can seem as a issue.
Comment 3 Chris Wilson 2012-11-22 09:20:53 UTC
It's a core vfs warning, so we can't touch it. The test could in theory be refactored, but it is a working test so I'd rather not...

The warning will only occur if something else executes on the box, which is a bad sign for a test machine.
Comment 4 Yi Sun 2012-11-22 09:50:14 UTC
We should just grep "drm:.*" in the dmesg.

Closing old verified.
