Yousuk Seung says: ==================== tcp: improve delivered counts in SCM_TSTAMP_ACK Currently delivered and delivered_ce in OPT_STATS of SCM_TSTAMP_ACK do not fully reflect the current ack being timestamped. Also they are not in sync as the delivered count includes packets being sacked and some of cumulatively acked but delivered_ce includes none. This patch series updates tp->delivered and tp->delivered_ce together to keep them in sync. It also moves generating SCM_TSTAMP_ACK to later in tcp_clean_rtx_queue() to reflect packets being cumulatively acked up until the current skb for sack-enabled connections. ==================== 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.
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.
