This series introduces simple usage and performance counters for the online fsck subsystem. The goal here is to enable developers and sysadmins to look at summary counts of how many objects were checked and repaired; what the outcomes were; and how much time the kernel has spent on these operations. The counter file is exposed in debugfs because that's easier than cramming it into the device model, and debugfs doesn't have rules against complex file contents, unlike sysfs. This has been running on the djcloud for months with no problems. Enjoy! Signed-off-by: Darrick J.

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.
