[Christoph Hellwig]

Hi Jens,

here are the first 60+ nvme patches for Linux 5.8:

 - NVMe over Fibre Channel protocol updates, which also reach over to
   drivers/scsi/lpfc (James Smart)
 - namespace revalidation support on the target (Anthony Iliopoulos)
 - gcc zero length array fix (Arnd Bergmann)
 - nvmet cleanups (Chaitanya Kulkarni)
 - misc cleanups and fixes (me, Keith Busch, Sagi Grimberg)
 - use a SRQ per completion vector (Max Gurtovoy)
 - fix handling of runtime changes to the queue count (Weiping Zhang)
