IB/ipoib: drop useless LIST_HEAD

2019-01-02T22:42:43+00:00

Drop LIST_HEAD where the variable it declares is never used.

Commit 31c02e215700 ("IPoIB: Avoid using stale last_send counter
when reaping AHs") removed the uses, but not the declaration.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// 
@@
identifier x;
@@
- LIST_HEAD(x);
  ... when != x
//

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"

 "This is mostly update of the usual drivers: smarpqi, lpfc, qedi,

  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"

RDMA/srpt: Use kmem_cache_free() instead of kfree()

2018-12-22T23:07:47+00:00

memory allocated by kmem_cache_alloc() should be freed using
kmem_cache_free(), not kfree().

RDMA: Mark if destroy address handle is in a sleepable context

2018-12-19T23:28:03+00:00

Introduce a 'flags' field to destroy address handle callback and add a
flag that marks whether the callback is executed in an atomic context or
not.

This will allow drivers to wait for completion instead of polling for it
when it is allowed.

RDMA/srpt: Add support for immediate data

2018-12-19T20:07:26+00:00

Modify allocation of the non-SRQ receive queues such that immediate
data is aligned on a 512 byte boundary. That alignment is necessary
to pass the immediate data without copying to the block layer. When
receiving an SRP_CMD with immediate data, postpone the ib_post_recv()
call until target_execute_cmd() has finished. See also
srpt_release_cmd().

RDMA/srpt: Remove driver version and release date

2018-12-19T20:07:26+00:00

Neither a driver version number nor a release data is useful in
an upstream driver. Remove the word "InfiniBand" from the driver
description because recently RoCE support has been added to this
driver.
