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 smaller cycle with many of the commits being smallish
code fixes and improvements across the drivers.
- Driver updates for bnxt_re, cxgb4, hfi1, hns, mlx5, nes, qedr, and
rxe
- Memory window support in hns
- mlx5 user API 'flow mutate/steering' allows accessing the full
packet mangling and matching machinery from user space
- Support inter-working with verbs API calls in the 'devx' mlx5 user
API, and provide options to use devx with less privilege
- Modernize the use of syfs and the device interface to use attribute
groups and cdev properly for uverbs, and clean up some of the core
code's device list management
- More progress on net namespaces for RDMA devices
- Consolidate driver BAR mmapping support into core code helpers and
rework how RDMA holds poitners to mm_struct for get_user_pages
cases
- First pass to use 'dev_name' instead of ib_device->name
- Device renaming for RDMA devices"
