Because Tiny srcu_read_unlock() directly calls swake_up_one(), lockdep complains when a pi lock is held across that srcu_read_unlock(). Although this is a lockdep false positive (there is no other CPU to complete the deadlock cycle), lockdep is what it is at the moment. This commit therefore prevents rcutorture from holding pi lock across a Tiny srcu_read_unlock(). Signed-off-by: Paul E. McKenney <paulmck@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 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.
