The current ODP counters represent the total number of pages handled, but it is not enough to understand the effectiveness of these operations. Extend the ODP counters to include the number of times page fault and invalidation events were handled. Example for a single page fault handling 512 pages: - page_fault: incremented by 512 (total pages) - page_fault_handled: incremented by 1 (operation count) The same example is applicable for page invalidation too. Previous output: $ rdma stat mr dev rocep8s0f0 mrn 8 page_faults 27 page_invalidations 0 page_prefetch 29 New output: $ rdma stat mr dev rocep8s0f0 mrn 21 page_faults 512 page_faults_handled 1 page_invalidations 0 page_invalidations_handled 0 page_prefetch 51200 Signed-off-by: Chiara Meiohas <cmeiohas@nvidia.com> Reviewed-by: Michael Guralnik <michaelgur@nvidia.com> Link: https://patch.msgid.link/b18f29ed1392996ade66e9e6c45f018925253f6a.1733234165.git.leonro@nvidia.com Signed-off-by: Leon Romanovsky <leon@kernel.org> |

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 reStructuredText 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.
