It's similar to a NFS client and it has a set of maintainers that you saw in the MAINTAINER file. drivers/target/iscsi/iscsi_target_util.c is another driver which is similar to a NFS server. Martin is the overall maintainer but it's a group effort to review patches. I've tested and reviewed the iscsi_tcp parts. You can add my: Reviewed-by: Mike Christie <michael.christie@xxxxxxxxxx> For the iscsi_target_util.c part, I'm reviewing it now and hoping Maurizio and/or Dimitry might review as well. One question on the target part I had is about the TODO above. Is that something you were going to do, or is it something you are asking the target people to do?
