[PATCHv2 0/7] libfc: sanitize kref and state machine fixes

[Hannes Reinecke <hare@suse.de>]

Hi all,

here is the first round of patch to fixup libfc and FCoE.
It consists of a rewrite of the libfc rport kref handling
(or, to be precise, is _implements_ rport kref handling)
and updates the 'disc_mutex' handling to match the new
kref usage.
There are also some state machine fixes to handle FLOGI
better and a fix from Chad to harden FCoE login.

As usual, comments and reviews are welcome.

Changes to v1:
- Fixup typo in fc_lport.c
- Add review tags where applicable

Chad Dupuis (2):
  libfc: Do not take rdata->rp_mutex when processing a -FC_EX_CLOSED ELS
    response.
  fcoe: Harden CVL handling when we have not logged into the fabric.

Hannes Reinecke (5):
  libfc: Revisit kref handling
  libfc: Fixup disc_mutex handling
  libfc: Do not drop down to FLOGI for fc_rport_login()
  libfc: Do not login if the port is already started
  libfc: don't advance state machine for incoming FLOGI
