accel/amdxdna: Fix notifier_wq flushing warning

[PATCH V1] accel/amdxdna: Fix notifier_wq flushing warning

Posted by Lizhi Hou 3 weeks, 4 days ago

Create notifier_wq with WQ_MEM_RECLAIM flag to fix the possible warning.

  workqueue: WQ_MEM_RECLAIM amdxdna_js:drm_sched_free_job_work [gpu_sched] is flushing !WQ_MEM_RECLAIM notifier_wq:0x0

Fixes: e486147c912f ("accel/amdxdna: Add BO import and export")
