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] WARNING: CPU: 0 PID: 8250 at kernel/workqueue.c:2644 check flush dependency+0xe0/0x144 Call trace: check flush dependency+0xe0/0x144 start flush work.constprop.0+0x1d0/0x2f0 flush work.isra.0+0x40/0xb0 flush work+0x14/0x30 hns roce v2 destroy qp+0xac/0x1e0 [hns roce hw v2] ib destroy qp user+0x9c/0x2b4 rdma destroy qp+0x34/0xb0 rpcrdma ep destroy+0x28/0xcc [rpcrdma] rpcrdma ep put+0x74/0xb4 [rpcrdma] rpcrdma xprt disconnect+0x1d8/0x260 [rpcrdma] xprt rdma connect worker+0xc0/0x120 [rpcrdma] process one work+0x1cc/0x4d0 worker thread+0x154/0x414 kthread+0x104/0x144 ret from fork+0x10/0x18

Since QP destruction frees memory, this wq should have the WQ MEM RECLAIM.
