lu_object maintains 2 lru counts. One is a per-bucket lsb_lru_len. The other is the per-cpu ls_lru_len_counter. The only times the per-bucket counters are use are: - a debug message when an object is added - in lu_site_stats_get when all the counters are combined. The debug message is not essential, and the per-cpu counter can be used to get the combined total. So discard the per-bucket lsb_lru_len.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
