That's a 2.6.4 patch which generates 100% rejects.

A suitable fix would be to make sure all the locking's tight and to convert DRM to use unlocked_ioctl. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
