A following patch introduces qevents, points in qdisc algorithm where packet can be processed by user-defined filters. Should this processing lead to a situation where a new packet is to be enqueued on the same port, holding the root lock would lead to deadlocks. To solve the issue, qevent handler needs to unlock and relock the root lock when necessary. To that end, add the root lock argument to the qdisc op enqueue, and propagate throughout.

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.
