In the Linux kernel, the following vulnerability has been resolved:

RDMA/hns: Fix WQ_MEM_RECLAIM warning

When sunrpc is used, if a reset triggered, our wq may lead the
following trace:

workqueue: WQ_MEM_RECLAIM xprtiod:xprt_rdma_connect_worker [rpcrdma]
is flushing !WQ_MEM_RECLAIM hns_roce_irq_workq:flush_work_handle
[hns_roce_hw_v2]

Since QP destruction frees memory, this wq should have the WQ_MEM_RECLAIM.
