Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2019-03-10T00:53:47+00:00

Pull SCSI updates from James Bottomley:
 "This is mostly update of the usual drivers: arcmsr, qla2xxx, lpfc,
  hisi_sas, target/iscsi and target/core.

  Additionally Christoph refactored gdth as part of the dma changes. The
  major mid-layer change this time is the removal of bidi commands and
  with them the whole of the osd/exofs driver and filesystem. This is a
  major simplification for block and mq in particular"

Pull rdma updates from Jason Gunthorpe:
 "This has been a slightly more active cycle than normal with ongoing
  core changes and quite a lot of collected driver updates.

   - Various driver fixes for bnxt_re, cxgb4, hns, mlx5, pvrdma, rxe

   - A new data transfer mode for HFI1 giving higher performance

   - Significant functional and bug fix update to the mlx5
     On-Demand-Paging MR feature

   - A chip hang reset recovery system for hns

   - Change mm->pinned_vm to an atomic64

   - Update bnxt_re to support a new 57500 chip

   - A sane netlink 'rdma link add' method for creating rxe devices and
     fixing the various unregistration race conditions in rxe's
     unregister flow

   - Allow lookup up objects by an ID over netlink

   - Various reworking of the core to driver interface:
       - drivers should not assume umem SGLs are in PAGE_SIZE chunks
       - ucontext is accessed via udata not other means
       - start to make the core code responsible for object memory
         allocation
       - drivers should convert struct device to struct ib_device via a
         helper
       - drivers have more tools to avoid use after unregister problems"

IB/iser: Fix dma_nents type definition

2019-03-04T19:40:25+00:00

The retured value from ib_dma_map_sg saved in dma_nents variable. To avoid
future mismatch between types, define dma_nents as an integer instead of
unsigned.

RDMA: Add and use rdma_for_each_port

2019-02-19T17:13:39+00:00

We have many loops iterating over all of the end port numbers on a struct
ib_device, simplify them with a for_each helper.

Make sure that the next time a response is sent to the initiator that the

scsi: RDMA/srpt: Rework I/O context allocation

2019-02-05T02:31:37+00:00

Instead of maintaining a list of free I/O contexts, use an sbitmap data
structure to track which I/O contexts are in use and which are free. This
makes the ib_srpt driver more consistent with other LIO drivers.
