RE: [Xen-devel] iscsi patch

[Brian Wolfe <brianw@xxxxxxxxxxxx>]

Have either of you used a linux based iSCSI target driver? If so, which
driver did you use? I've found 4 so far and none of them will compile
cleanly against my fileserver running 2.6.8 8-(.

Second, do any of them export  a block device instead of the common file
and scsi block device?
