Jamal Hadi Salim says: ==================== net/sched: Retire some tc qdiscs and classifiers The CBQ + dsmark qdiscs and the tcindex + rsvp classifiers have served us for over 2 decades. Unfortunately, they have not been getting much attention due to reduced usage. While we dont have a good metric for tabulating how much use a specific kernel feature gets, for these specific features we observed that some of the functionality has been broken for some time and no users complained. In addition, syzkaller has been going to town on most of these and finding issues; and while we have been fixing those issues, at times it becomes obvious that we would need to perform bigger surgeries to resolve things found while getting a syzkaller fix in place. After some discussion we feel that in order to reduce the maintenance burden it is best to retire them. This patchset leaves the UAPI alone. I could send another version which deletes the UAPI as well. AFAIK, this has not been done before - so it wasnt clear what how to handle UAPI. It seems legit to just delete it but we would need to coordinate with iproute2 (given they sync up with kernel uapi headers). There are probably other users we don't know of that copy kernel headers. If folks feel differently I will resend the patches deleting UAPI for these qdiscs and classifiers. I will start another thread on iproute2 before sending any patches to iproute2. ==================== Link: https://lore.kernel.org/r/20230214134915.199004-1-jhs@mojatatu.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 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.
