This branch is shared with the rdma.git for dependencies in following patches: ==================== In order to hoist the interval tree code out of the drivers and into the mmu_notifiers it is necessary for the drivers to not use the interval tree for other things. This series replaces the interval tree with an xarray and along the way re-aligns all the locking to use a sensible SRCU model where the 'update' step is done by modifying an xarray. The result is overall much simpler and with less locking in the critical path. Many functions were reworked for clarity and small details like using 'imr' to refer to the implicit MR make the entire code flow here more readable. This also squashes at least two race bugs on its own, and quite possibily more that haven't been identified. ==================== * branch 'odp_rework': RDMA/odp: Remove broken debugging call to invalidate_range RDMA/mlx5: Do not race with mlx5_ib_invalidate_range during create and destroy RDMA/mlx5: Do not store implicit children in the odp_mkeys xarray RDMA/mlx5: Rework implicit ODP destroy RDMA/mlx5: Avoid double lookups on the pagefault path RDMA/mlx5: Reduce locking in implicit_mr_get_data() RDMA/mlx5: Use an xarray for the children of an implicit ODP RDMA/mlx5: Split implicit handling from pagefault_mr RDMA/mlx5: Set the HW IOVA of the child MRs to their place in the tree RDMA/mlx5: Lift implicit_mr_alloc() into the two routines that call it RDMA/mlx5: Rework implicit_mr_get_data RDMA/mlx5: Delete struct mlx5_priv->mkey_table RDMA/mlx5: Use a dedicated mkey xarray for ODP RDMA/mlx5: Split sig_err MR data into its own xarray RDMA/mlx5: Use SRCU properly in ODP prefetch |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
