For PREEMPT_RCU, the rcu_exp_handler() function checks whether the current CPU is in idle, by calling rcu_dynticks_curr_cpu_in_eqs(). However, rcu_exp_handler() is called in IPI handler context. So, it should be checking the idle context using rcu_is_cpu_rrupt_from_idle(). Fix this by using rcu_is_cpu_rrupt_from_idle() instead of rcu_dynticks_curr_cpu_in_eqs(). Non-preempt configuration already uses the correct check. Reviewed-by: Frederic Weisbecker <frederic@kernel.org> Signed-off-by: Neeraj Upadhyay <quic_neeraju@quicinc.com> Signed-off-by: Paul E.

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.
