The patchset is based on 6.4/scsi-staging branch. The first 11 patches are just a refactoring to reduce code duplication in fabric drivers. They make several callouts be optional in fabric ops. Make a default implementation of the optional ops and remove such implementations in the fabric drivers. The last patch is a new virtual remote fabric driver. It have a valueble sence with patchset "scsi: target: make RTPI an TPG identifier" to configure RPTI on remote/tpgt_x same as on tpgt_y on other nodes in a storage cluster. That allows to report the same ports in RTPG from each node and to have a clusterwide tpg/acl/lun view in kernel. On its own it can be used as a dummy fabric driver for test purposes or whatever.
