Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe:
"This has been a large cycle for RDMA, with several major patch series
reworking parts of the core code.
- Rework the so-called 'gid cache' and internal APIs to use a kref'd
pointer to a struct instead of copying, push this upwards into the
callers and add more stuff to the struct. The new design avoids
some ugly races the old one suffered with. This is part of the
namespace enablement work as the new struct is learning to be
namespace aware.
- Various uapi cleanups, moving more stuff to include/uapi and fixing
some long standing bugs that have recently been discovered.
- Driver updates for mlx5, mlx4 i40iw, rxe, cxgb4, hfi1, usnic,
pvrdma, and hns
- Provide max_send_sge and max_recv_sge attributes to better support
HW where these values are asymmetric.
- mlx5 user API 'devx' allows sending commands directly to the device
FW, instead of trying to cram every wild and niche feature into the
common API. Sort of like what GPU does.
- Major write() and ioctl() API rework to cleanly support PCI device
hot unplug and advance the ioctl conversion work
- Sparse and compile warning cleanups
- Add 'const' to the ib_poll_cq() signature, and permit a NULL
'bad_wr', which is the common use case
- Various patches to avoid high order allocations across the stack
- SRQ support for cxgb4, hns and qedr
- Changes to IPoIB to better follow the netdev model for working with
struct net_device liftime"
