   nvme-tcp (me)
 - fix nvme-loop to handle multi-page segments (Ming)
 - fix error handling in the nvmet configfs code (Max)
 - add a missing requeue point in the multipath code (Martin George)"

* 'nvme-5.1' of git://git.infradead.org/nvme:
  nvmet: fix error flow during ns enable
  nvmet: fix building bvec from sg list
