Due to the conversion of the NOHZ timer placement to a pull at expiry time model, the per CPU timer bases with non pinned timers are no longer handled only by the local CPU. In case a remote CPU already expires the non pinned timers base of the local CPU, nothing more needs to be done by the local CPU. A check at the begin of the expire timers routine is required, because timer base lock is dropped before executing the timer callback function. This is a preparatory work, but has no functional impact right now.

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.
