The schedule_delayed_monitor_work() function relies on the count of objects queued into any given kfree_rcu_cpu structure. This count is used to determine how quickly to schedule passing these objects to RCU. There are three pipes where pointers can be placed. When any pipe is offloaded, the kfree_rcu_cpu structure's ->count counter is set to zero, which is wrong because the other pipes might still be non-empty. This commit therefore maintains per-pipe counters, and introduces a krc_count() helper to access the aggregate value of those counters.

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.
