This patchset implements an online checker for the realtime summary file. The first few changes are some general cleanups -- scrub should get its own references to all inodes, and we also wrap the inode lock functions so that we can standardize unlocking and releasing inodes that are the focus of a scrub. With that out of the way, we move on to constructing a shadow copy of the rtsummary information from the rtbitmap, and compare the new copy against the ondisk copy. This has been running on the djcloud for years 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.
