[PATCH v1 0/6] nvme-fc: fix blktests nvme/041

[Daniel Wagner <dwagner@suse.de>]

I've dropped the rport ref counting change in the main patch and gave it another
round of testing. This time with dev_loss_tmo active with SCSI and NVME enabled
on the same rport. Nothing exploded, all resources were released correctly.

I am not so happy with the 'connect_sync' name yet (patch #1) but we still have
to agree on that offloading the initial connect attemp is correct. James and
Hannes are strongly in favour for this approach as far I can tell.

changes:
v1:
 - renamed 'nvme-fc: redesign locking and refcounting'
   to 'nvme-fc: reorder ctrl ref counting and cleanup code path'
 - testing with scsi/nvme dev_loss_tmo on real hw
 - removed rport ref counting part
 - collected RB tags
v0:
 - initial version
 - https://lore.kernel.org/linux-nvme/20240216084526.14133-1-dwagner@suse.de/

Daniel Wagner (6):
  nvme-fabrics: introduce connect_sync option
  nvme-fc: rename free_ctrl callback to match name pattern
  nvme-fc: do not retry when auth fails or connection is refused
  nvme-fabrics: introduce ref counting for nvmf_ctrl_options
  nvme-fc: reorder ctrl ref counting and cleanup code path
  nvme-fc: wait for connect attempt to finish
