Some kernel configurations prohibit invoking local_bh_enable() while interrupts are disabled. However, refscale disables interrupts to reduce OS noise during the tests, which results in splats. This commit therefore adds an ->enable_irqs flag to the ref_scale_ops structure, and refrains from disabling interrupts when that flag is set. This flag is set for the "bh" and "incpercpubh" scale_type module-parameter values. Signed-off-by: Paul E. McKenney <paulmck@kernel.org> Signed-off-by: Frederic Weisbecker <frederic@kernel.org>
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.
