Extend the RDMA nldev return a context information, like ctx number and process ID that created that context. This functionality is helpful to find orphan contexts that are not closed for some reason. Sample output: $ rdma res show ctx dev ibp8s0f0 ctxn 0 pid 980 comm ibv_rc_pingpong dev ibp8s0f0 ctxn 1 pid 981 comm ibv_rc_pingpong dev ibp8s0f0 ctxn 2 pid 992 comm ibv_rc_pingpong dev ibp8s0f1 ctxn 0 pid 984 comm ibv_rc_pingpong dev ibp8s0f1 ctxn 1 pid 987 comm ibv_rc_pingpong $ rdma res show ctx dev ibp8s0f1 dev ibp8s0f1 ctxn 0 pid 984 comm ibv_rc_pingpong dev ibp8s0f1 ctxn 1 pid 987 comm ibv_rc_pingpong Link: https://lore.kernel.org/r/5c956acfeac4e9d532988575f3da7d64cb449374.1618753110.git.leonro@nvidia.com Signed-off-by: Neta Ostrovsky <netao@nvidia.com> Reviewed-by: Mark Zhang <markzhang@nvidia.com> Signed-off-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
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.
