Pull rdma updates from Jason Gunthorpe:
 "This has been a fairly typical cycle, with the usual sorts of driver
  updates. Several series continue to come through which improve and
  modernize various parts of the core code, and we finally are starting
  to get the uAPI command interface cleaned up.

   - Various driver fixes for bnxt_re, cxgb3/4, hfi1, hns, i40iw, mlx4,
     mlx5, qib, rxe, usnic

   - Rework the entire syscall flow for uverbs to be able to run over
     ioctl(). Finally getting past the historic bad choice to use
     write() for command execution

   - More functional coverage with the mlx5 'devx' user API

   - Start of the HFI1 series for 'TID RDMA'

   - SRQ support in the hns driver

   - Support for new IBTA defined 2x lane widths

   - A big series to consolidate all the driver function pointers into a
     big struct and have drivers provide a 'static const' version of the
     struct instead of open coding initialization

   - New 'advise_mr' uAPI to control device caching/loading of page
     tables

   - Support for inline data in SRPT

   - Modernize how umad uses the driver core and creates cdev's and
     sysfs files

   - First steps toward removing 'uobject' from the view of the drivers"

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

2018-12-28T22:48:06+00:00

Pull SCSI updates from James Bottomley:
 "This is mostly update of the usual drivers: smarpqi, lpfc, qedi,
  megaraid_sas, libsas, zfcp, mpt3sas, hisi_sas.

  Additionally, we have a pile of annotation, unused variable and minor
  updates.

  The big API change is the updates for Christoph's DMA rework which
  include removing the DISABLE_CLUSTERING flag.

  And finally there are a couple of target tree updates"

scsi: flip the default on use_clustering

2018-12-19T04:13:12+00:00

Most SCSI drivers want to enable "clustering", that is merging of
segments so that they might span more than a single page.  Remove the
ENABLE_CLUSTERING define, and require drivers to explicitly set
DISABLE_CLUSTERING to disable this feature.

Merge tag 'v4.20-rc6' into rdma.git for-next

2018-12-11T21:24:57+00:00

For dependencies in following patches.

IB/core: Make function ib_fmr_pool_unmap return void

2018-11-21T23:13:02+00:00

Since the function always returns 0 make it void.

iser: set sector for ambiguous mr status errors

2018-11-21T23:03:43+00:00

If for some reason we failed to query the mr status, we need to make sure
to provide sufficient information for an ambiguous error (guard error on
sector 0).

IB/iser: Fix possible NULL deref at iser_inv_desc()

2018-09-28T15:53:49+00:00

In case target remote invalidates bogus rkey and signature is not used,
pi_ctx is NULL deref.

The commit also fails the connection on bogus remote invalidation.

RDMA/ulp: Use dev_name instead of ibdev->name

2018-09-26T19:51:48+00:00

These return the same thing but dev_name is a more conventional use of the
kernel API.
