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 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"
