[PATCHv2 0/3] nvmet: unique discovery subsystem

[Hannes Reinecke]

Hi all,

here's my next attempt to support unique discovery subsystems.
The main idea is to make the subsystem type configurable; if it's being
set to 'discovery' it'll replace the static discovery subsystem.
The admin then need to configure the subsystem as normal by linking
it into the ports where the discovery subsystem should be visible.
And the discovery log then includes all configured ports to all
configured subsystems, as usual modified by whether the host may
access this subsystem or not.

As usual, comments and reviews are welcome.

Changes to the original submission:
- Include all subsystems in the discovery log output

Hannes Reinecke (3):
  nvmet: check for subsystem type in nvmet_find_get_subsys()
  nvmet: make the subsystem type configurable
  nvmet: include all configured ports in discovery log page for unique
    discover controller
