Well, arguably we may want to support both ways. Having iSCSI target 
running in userland completely has some serious advantages (security is 
a big one for example, as you can run daemon easily as unprivileged 
process). The kernel iSCSI target only makes sense for really 
performance-constrained cases, and hopefully sooner or later we will be 
able to narrow the gap by utilizing zero-copy interfaces.
