Previously, shared blocks were only relevant for the pseudo-qdiscs ingress and clsact. Recently, a qevent facility was introduced, which allows to bind blocks to well-defined slots of a qdisc instance. RED in particular got two qevents: early_drop and mark. Drivers that wish to offload these blocks will be sent the usual notification, and need to know which qdisc it is related to. To that end, extend flow_block_offload with a "sch" pointer, and initialize as appropriate. This prompts changes in the indirect block facility, which now tracks the scheduler in addition to the netdevice. Update signatures of several functions similarly.

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.
