Subject: [GIT PULL] Please pull RDMA subsystem changes
Hi Linus,
Usual basic set of driver updates. Some common code improvements for
DMA Handle, MAD flow control and namespacing.
There is a small merge conflict, resolve it with:
$ git rm drivers/infiniband/hw/qib/qib_sysfs.c
Ther are now three new drivers on the list, hopefully some will come
through on the next cycle.
Thanks,
Jason
The following changes since commit 9a0048e0ae14cb7babfd459ec920234e8a2ab86e:

RDMA/siw: Change maintainer email address (2025-07-24 03:20:47 -0400)
----------------------------------------------------------------
RDMA v6.17 merge window pull request
- Various minor code cleanups and fixes for hns, iser, cxgb4, hfi1, rxe,
erdma, mana_ib
- Prefetch supprot for rxe ODP
- Remove memory window support from hns as new device FW is no longer
support it
- Remove qib, it is very old and obsolete now, Cornelis wishes to
restructure the hfi1/qib shared layer
- Fix a race in destroying CQs where we can still end up with work running
because the work is cancled before the driver stops triggering it
- Improve interaction with namespaces.
* Follow the devlink namespace for newly spawned RDMA devices
* Create iopoib net devces in the parent IB device's namespace
* Allow CAP_NET_RAW checks to pass in user namespaces
- A new flow control scheme for IB MADs to try and avoid queue overflows
in the network
- Fix 2G message sizes in bnxt_re
- Optimize mkey layout for mlx5 DMABUF
- New "DMA Handle" concept to allow controlling PCI TPH and steering tags
