Paolo Abeni 4b943faedf udp/v6: prefetch rmem_alloc in udp6_queue_rcv_skb() very similar to commit `dd99e425be` ("udp: prefetch rmem_alloc in udp_queue_rcv_skb()"), this allows saving a cache miss when the BH is bottle-neck for UDP over ipv6 packet processing, e.g. for small packets when a single RX NIC ingress queue is in use. Performances under flood when multiple NIC RX queues used are unaffected, but when a single NIC rx queue is in use, this gives ~8% performance improvement.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
