If anyone has any objections, please let me know. ------------------ From: Leon Romanovsky [ Upstream commit d43b1c17f9e1b9d34a0d742f569c00d84147ebc0 ] hfi1 does not queue work on ib_wq. QSFP and link work run on the per-port link_wq, while the remaining device work uses hfi1_wq or dedicated queues. The probe failure path destroys both per-port workqueues, and normal device removal flushes them in shutdown_device() before destroying them. Remove the flushes of the core-owned global workqueue. Waiting for unrelated core or other device work is not part of hfi1 teardown.
