Cong Wang says: ==================== net_sched: reduce the number of qdisc resets This patchset aims to reduce the number of qdisc resets during qdisc tear down. Patch 1~3 are preparation for their following patches, especially patch 2 and patch 3 add a few tracepoints so that we can observe the whole lifetime of qdisc's. Patch 4 and patch 5 are the ones do the actual work. Please find more details in each patch description. Vaclav Zindulka tested this patchset and his large ruleset with over 13k qdiscs defined got from 22s to 520ms. ==================== 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.
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.
