[PATCHv4 0/7] nvmet: debugfs support

[Hannes Reinecke]

Hi all,

taking up the original patchset for nvmet debugfs
I've improved upon that submission by modifying
the layout:

/dev/kernel/debug/nvmet
  <subsysnqn>
    ctrl<cntlid>
      port
      state
      hostnqn
      kato
      host_traddr

The 'state' attribute is the value of the
CSTS register; one can trigger a controller reset
by writing 'fatal' into it (to set CSTS.CFS).

As usual, comments and reviews are welcome.

Changes to v3:
- drop patch to add queue entries
- Reviews from Sagi

Changes to v2:
- Move the 'host_traddr' attribute to the
  controller directory
- Rename callback to 'host_traddr'

Hannes Reinecke (7):
  nvmet: add debugfs support
  nvmet: add 'host_traddr' callback for debugfs
  nvmet-tcp: implement host_traddr()
  nvmet-rdma: implement host_traddr()
  nvmet-fc: implement host_traddr()
  nvme-fcloop: implement 'host_traddr'
  lpfc_nvmet: implement 'host_traddr'
