Linux kernel source tree
a22b7388d6
Peek at old qdisc and graft only when deleting a leaf class in the htb,
rather than when deleting the htb itself. Do not peek at the qdisc of the
netdev queue when destroying the htb. The caller may already have grafted a
new qdisc that is not part of the htb structure being destroyed.
This fix resolves two use cases.
1. Using tc to destroy the htb.
- Netdev was being prematurely activated before the htb was fully
destroyed.
2. Using tc to replace the htb with another qdisc (which also leads to
the htb being destroyed).
- Premature netdev activation like previous case. Newly grafted qdisc
was also getting accidentally overwritten when destroying the htb.

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.
