Implement the only missing part for scrub: RAID56 P/Q stripe scrub. The workflow is pretty straightforward for the new function, scrub_raid56_parity_stripe(): - Go through the regular scrub path for each data stripe - Wait for the verification and repair to finish - Writeback the repaired sectors to data stripes - Make sure all stripes are properly repaired If we have sectors unrepaired, we cannot continue, or we could further corrupt the P/Q stripe. - Submit the rbio for P/Q stripe The dev-replace would be handled inside raid56_parity_submit_scrub_rbio() path. - Wait for the above bio to finish Although the old code is no longer used, we still keep the declaration, as the cleanup can be several times larger than this patch itself.

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.
