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) are available in the Git repository at: git://git.infradead.org/nvme.git nvme-5.2 for you to fetch changes up to d0de579c043c3a2ab60ce75eb6cf4d414becc676: 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: only call nvme_unmap_data for requests transferring data nvme-pci: do not build a scatterlist to map metadata nvme-pci: split metadata handling from nvme_map_data / nvme_unmap_data nvme-pci: remove the inline scatterlist optimization nvme-pci: optimize mapping of small single segment requests nvme-pci: optimize mapping single segment requests using SGLs nvme-pci: tidy up nvme_map_data Gustavo A.
