Some qdiscs like taprio turn out to be actually pretty reliant on a well configured stab, to not underestimate the skb transmission time (by properly accounting for L1 overhead). In a future change, taprio will need the stab, if configured by the user, to be available at ops->init() time. It will become even more important in upcoming work, when the overhead will be used for the queueMaxSDU calculation that is passed to an offloading driver. However, rcu_assign_pointer(sch->stab, stab) is called right after ops->init(), making it unavailable, and I don't really see a good reason for that. Move it earlier, which nicely seems to simplify the error handling path as well.

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.
