Thresholds can increase the number of counters a metric needs. The NMI watchdog can take away a counter (hopefully the buddy watchdog will become the default and this will no longer be true). Add a new constraint for the case that a metric and its thresholds would fit in counters but only if the NMI watchdog isn't enabled. Either the threshold or the NMI watchdog should be disabled to make the metric fit. Wire this up into the metric__group_events logic.

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.
