====================
net_sched: Adapt qdiscs for reentrant enqueue cases

As described in Gerrard's report [1], there are cases where netem can
make the qdisc enqueue callback reentrant. Some qdiscs (drr, hfsc, ets,
qfq) break whenever the enqueue callback has reentrant behaviour.
This series addresses these issues by adding extra checks that cater for
these reentrant corner cases. This series has passed all relevant test
cases in the TDC suite.

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 reStructuredText 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.
