Re: [PATCH 3/3] MidLayer updates - extending scsi_target support

[Vladislav Bolkhovitin <vst@vlnb.net>]

Please, forgive me my ignorance, it looks like something was happened 
"behind the scene" (linux-scsi list), and I missed it. Is support for 
SCSI targets started to be added in Linux? I mean "SCSI targets" as the 
ability to export local devices on a SCSI bus. If so, please consider 
proposed SCSI target mid-level (SCST) living on 
http://scst.sourceforge.net. In the next few weeks we are going to clean 
it a bit and prepare the patch, so it could start being part of some 
testing tree, probably "-mm", although it is stable enough ever for 
Linus one.

BTW, are there any descriptions for current scsi_target support and in 
which direction it's moving?
