[PATCH v3 00/12] add virtual remote fabric

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
