Hi Jens,
below is the first batch of nvme updates for 5.2. This includes the
performance improvements for single segment I/O on PCIe, which introduce
new block helpers, so it might be a good idea to get them in early.
- various performance optimizations in the PCIe code (Keith and me)
- new block helpers to support the above (me)
- nvmet error conversion cleanup (me)
- nvmet-fc variable sized array cleanup (Gustavo)
- passthrough ioctl error printk cleanup (Kenneth)
- small nvmet fixes (Max)
- endianess conversion cleanup (Max)
- nvmet-tcp faspath completion optimization (Sagi)
The following changes since commit 2b24e6f63ac9e817630424c6d8f008256348dfc4:
block: bio: ensure newly added bio flags don't override BVEC_POOL_IDX (2019-04-04 09:30:37 -0600)

nvme: log the error status on Identify Namespace failure (2019-04-05 08:07:58 +0200)
----------------------------------------------------------------
Christoph Hellwig (15):
nvmet: avoid double errno conversions
block: add a req_bvec helper
block: add a rq_integrity_vec helper
block: add a rq_dma_dir helper
block: add dma_map_bvec helper
nvme-pci: remove nvme_init_iod
nvme-pci: move the call to nvme_cleanup_cmd out of nvme_unmap_data
nvme-pci: merge nvme_free_iod into nvme_unmap_data

nvme-pci: tidy up nvme_map_data
Gustavo A. R. Silva (1):
nvmet-fc: use zero-sized array and struct_size() in kzalloc()
Keith Busch (3):
nvme-pci: use a flag for polled queues
nvme-pci: remove q_dmadev from nvme_queue
nvme-pci: remove unused nvme_iod member
Kenneth Heitke (1):
nvme: log the error status on Identify Namespace failure
Max Gurtovoy (3):
nvme: avoid double dereference to convert le to cpu
