Eric Dumazet says: ==================== net_sched: speedup qdisc dequeue Avoid up to two cache line misses in qdisc dequeue() to fetch skb_shinfo(skb)->gso_segs/gso_size while qdisc spinlock is held. Idea is to cache gso_segs at enqueue time before spinlock is acquired, in the first skb cache line, where we already have qdisc_skb_cb(skb)->pkt_len. This series gives a 8 % improvement in a TX intensive workload. (120 Mpps -> 130 Mpps on a Turin host, IDPF with 32 TX queues) v2: https://lore.kernel.org/netdev/20251111093204.1432437-1-edumazet@google.com/ v1: https://lore.kernel.org/netdev/20251110094505.3335073-1-edumazet@google.com/T/#m8f562ed148f807c02fd02c6cd243604d449615b9 ==================== Link: https://patch.msgid.link/20251121083256.674562-1-edumazet@google.com Signed-off-by: Paolo Abeni <pabeni@redhat.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 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.
