Subject: [GIT PULL] Please pull RDMA subsystem changes
Hi Linus,
The PR has a couple of branches you've already merged, irdma updates
went through netdev, the DMA API core changes went through the DMA
tree and there is a merge of v6.15 because of dependencies in a
last-minute bug fix.
This includes one of three launch users for the new two step DMA API,
the ODP hmm conversion and hmm helpers.
Otherwise fairly typical driver updates.
Thanks,
Jason

RDMA/cma: Fix hang when cma_netevent_callback fails to queue_work (2025-05-26 15:36:46 -0300)
----------------------------------------------------------------
RDMA v6.16 merge window pull request
Usual collection of driver fixes:
- Small bug fixes and cleansup in hfi, hns, rxe, mlx5, mana siw
- Further ODP functionality in rxe
- Remote access MRs in mana, along with more page sizes
- Improve CM scalability with a rwlock around the agent
- More trace points for hns
- ODP hmm conversion to the new two step dma API
- Support the ethernet HW device in mana as well as the RNIC
- Cleanups:
* Use secs_to_jiffies() when appropriate
* Use ERR_CAST() instead of naked casts
* Don't use %pK in printk
* Unusued functions removed
* Allocation type matching
