This patch modifies struct ceph_client_metric so that each metric block (read, write and metadata) becomes an element in a array. This allows to also re-write the helper functions that handle these blocks, making them simpler and, above all, reduce the amount of copy&paste every time a new metric is added. Thus, for each of these metrics there will be a new struct ceph_metric entry that'll will contain all the sizes and latencies fields (and a lock). Note however that the metadata metric doesn't really use the size_fields, and thus this metric won't be shown in the debugfs '../metrics/size' file.

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.
