[RETURN VALUE OVERWRITE]
Inside scrub_stripe(), we would submit all the remaining stripes after
iterating all extents.
But since flush_scrub_stripes() can return error, we need to avoid
overwriting the existing @ret if there is any error.
However the existing check is doing the wrong check:
ret2 = flush_scrub_stripes();
if (!ret2)
ret = ret2;
This would overwrite the existing @ret to 0 as long as the final flush
detects no critical errors.
[FIX]
We should check @ret other than @ret2 in that case.

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.
