Currently we calculate the total amount of flash only devices dirty data by adding the dirty data of each flash only device under registering locker. It is very inefficient. In this patch, we add a member flash_dev_dirty_sectors in struct cache_set to record the total amount of flash only devices dirty data in real time, so we didn't need to calculate the total amount of dirty data any more.

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.
