Johannes Berg 6ee0270943 wifi: mac80211_hwsim: use hrtimer_active()
Instead of hrtimer_is_queued(), use hrtimer_active() since
it might be running concurrently, and then it's not queued
at that point in time, as suggested by Thomas Gleixner in
https://lore.kernel.org/87plqn5psu.ffs@tglx, I just never
got to this for ages.

I think the concurrency is otherwise fine since we'll get
to cancel if we're actually removing things, and otherwise
we just send a beacon at slightly the wrong time or so.

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.
