rcu/tree: Count number of batched kfree_rcu() locklessly
We can relax the correctness of counting of number of queued objects in favor of not hurting performance, by locklessly sampling per-cpu counters. This should be Ok since under high memory pressure, it should not matter if we are off by a few objects while counting. The shrinker will still do the reclaim.

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.
