Hello Paolo,

Thank you for having shared your kernel config off-list. After having
made the following changes to your kernel config I was able to run the
srp-test software:
* Enable CONFIG_DM_MULTIPATH_QL, CONFIG_DM_MULTIPATH_ST,
  CONFIG_SCSI_DH_RDAC, CONFIG_SCSI_DH_EMC and CONFIG_SCSI_DH_ALUA.
* Disable CONFIG_KASAN. Apparently there is an incompatibility between the
  rdma_rxe driver and KASAN. I'm still analyzing this.

Please let me know whether these changes also allow you to run the srp-test
software and whether you can reproduce what I reported at the start of this
e-mail thread.

Thanks,

Bart.
