[PATCH for-next v2 0/3] RDMA/rtrs: bugfix and cleanups

From: Li Zhijian
Date: Sat Apr 22 2023 - 21:27:34 EST


V2:
- Add new patch2 to fix a memory leak
- rewrite original patch2 to patch3 by refactoring the cleanup path instead of
introducing a new flag
- Drop original patch3: RDMA/rtrs: Fix use-after-free in rtrs_clt_rdma_cm_handler
The problem it tried to addressing doesn't appear after the new patch3
where it adjust the cleanup order

It's trying to fix 1 issue triggered by the following script which
connect/disconnect rnbd frequently.

# cat rnbd-self.sh
#!/bin/bash

/root/rpma/tools/config_softroce.sh eth0
modprobe rnbd_server
modprobe rnbd_client

while true;
do
echo "sessname=xyz path=ip:<server-ip> device_path=/dev/nvme0n1" > /sys/devices/virtual/rnbd-client/ctl/map_device
for i in /sys/block/rnbd*/rnbd/unmap_device
do
echo "normal" > $i
done
done
