[PATCH vfio-next 0/3] mlx5 VFIO PCI DMA conversion

[Leon Romanovsky <leon@kernel.org>]

Hi Alex,

This series presents subset of new DMA-API patchset [1] specific
for VFIO subsystem, with some small changes:
1. Change commit message in first patch.
2. Removed WARN_ON_ONCE DMA_NONE checks from third patch.

------------------------------------------------------------------
It is based on Marek's dma-mapping-for-6.16-two-step-api branch, so merging
now will allow us to reduce possible rebase errors in mlx5 vfio code and give
enough time to start to work on second driver conversion. Such conversion will
allow us to generalize the API for VFIO kernel drivers, in similar way that
was done for RDMA, HMM and block layers.

Thanks

  vfio/mlx5: Explicitly use number of pages instead of allocated length
  vfio/mlx5: Rewrite create mkey flow to allow better code reuse
  vfio/mlx5: Enable the DMA link API
