Merge patch series "add virtual remote fabric"
Dmitry Bogdanov <d.bogdanov@yadro.com> says:
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 has 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.
