![]() This commit extends the RDMA kernel verbs ABI to support the flush operation defined in IBA A19.4.1. These changes are backward compatible with the existing RDMA kernel verbs ABI. It makes device/HCA support new FLUSH attributes/capabilities, and it also makes memory region support new FLUSH access flags. Users can use ibv_reg_mr(3) to register flush access flags. Only the access flags also supported by device's capabilities can be registered successfully. Once registered successfully, it means the MR is flushable. Similarly, A flushable MR should also have one or both of GLOBAL_VISIBILITY and PERSISTENT attributes/capabilities like device/HCA.

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.
