Yuchung Cheng says: ==================== tcp: new mechanism to ACK immediately This patch is a follow-up feature improvement to the recent fixes on the performance issues in ECN (delayed) ACKs. Many of the fixes use tcp_enter_quickack_mode routine to force immediate ACKs. However the routine also reset tracking interactive session. This is not ideal because these immediate ACKs are required by protocol specifics unrelated to the interactiveness nature of the application. This patch set introduces a new flag to send a one-time immediate ACK without changing the status of interactive session tracking. With this patch set the immediate ACKs are generated upon these protocol states: 1) When a hole is repaired 2) When CE status changes between subsequent data packets received 3) When a data packet carries CWR flag ==================== Signed-off-by: David S.

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.
