This patch splits the lists of objects so as to avoid sending any through RCU that have already been queued for more than one grace period. These long-term-resident objects are immediately freed. The remaining short-term-resident objects are queued for later freeing using queue_rcu_work(). This change avoids delaying workqueue handlers with synchronize_rcu() invocations. Yes, workqueue handlers are designed to handle blocking, but avoiding blocking when unnecessary improves performance during low-memory situations.

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.
