Relieve contention on sc_rw_ctxt_lock by converting rdma->sc_rw_ctxts to an llist. The goal is to reduce the average overhead of Send completions, because a transport's completion handlers are single-threaded on one CPU core. This change reduces CPU utilization of each Send completion by 2-3% on my server. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Reviewed-By: Tom Talpey <tom@talpey.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.
