[PATCHv2 0/7] nvmet: debugfs support

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
      queue<qnum>
        host_traddr
	sqsize
	sqhead

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.
