If a dma-fence submission has in-fences and pagefault queues are running work, there is little incentive to kick the pagefault queues off the hardware until the dma-fence submission is ready to run. Therefore, wait on the in-fences of the dma-fence submission before removing the pagefault queues from the hardware. v2: - Fix kernel doc (CI) - Don't wait under lock (Thomas) - Make wait interruptable Suggested-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patch.msgid.link/20251212182847.1683222-6-matthew.brost@intel.com
