Doc Text:
.The RADOS Block Device handler correctly parses configuration strings Previously, the RADOS Block Device (RBD) handler used the `strtok()` function while parsing configuration strings, which is not thread-safe. This caused incorrect parsing of the configuration string of image names when creating or reopening an image. This resulted in the image failing to open. With this release, the RBD handler uses the thread-safe `strtok_r()` function, allowing for the correct parsing of configuration strings.

Comment 8 Preethi 2021-10-04 12:37:46 UTC 
Was not able to see the below issue with tcmu-runner-1.5.4-2.el8cp and with the latest ceph build. 

"2021-09-01 12:27:55.526 3154 [ERROR] tcmu_rbd_open:877 rbd/igw-hdd-01.vmw-hdd-scratch-01: Could not get image name
2021-09-01 12:27:56.529 3154 [ERROR] tcmu_acquire_dev_lock:395 rbd/igw-hdd-01.vmw-hdd-scratch-01: Could not reopen "

Below are the steps followed
1) Configured ISCSI with 4 gateways collocated with OSDs
2) Created 100GB disk 
3) Having ESXi Initiator, Created VMFS datastore and RAN IOs 
4) While IOs are running, performed HA 

Latest build has passed the QE standard ISCSI test, hence, moving this to be verified after discussing with @Ilya Dryomov as the issue is rarely reproduceable and there are no proper steps to verify.
