Paolo Abeni says: ==================== sched: refactor NOLOCK qdiscs With the introduction of NOLOCK qdiscs, pfifo_fast performances in the uncontended scenario degraded measurably, especially after the commit eb82a9944792 ("net: sched, fix OOO packets with pfifo_fast"). This series restore the pfifo_fast performances in such scenario back the previous level, mainly reducing the number of atomic operations required to perform the qdisc_run() call. Even performances in the contended scenario increase measurably. Note: This series is on top of: sched: manipulate __QDISC_STATE_RUNNING in qdisc_run_* helpers ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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. See Documentation/00-INDEX for a list of what is contained in each file. 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.
