The value mr->sig is stored in the entry upon mr allocation, however, ibmr is wrongly entered here as "old", therefore, xa_cmpxchg() does not replace the entry with NULL, which leads to the following trace: WARNING: CPU: 28 PID: 2078 at drivers/infiniband/hw/mlx5/main.c:3643 mlx5_ib_stage_init_cleanup+0x4d/0x60 [mlx5_ib] Modules linked in: nvme_rdma nvme_fabrics nvme_core 8021q garp mrp bonding bridge stp llc rfkill rpcrdma sunrpc rdma_ucm ib_srpt ib_isert iscsi_tad CPU: 28 PID: 2078 Comm: reboot Tainted: G X --------- --- 5.13.0-0.rc2.19.el9.x86_64 #1 Hardware name: Dell Inc.
