[ Upstream commit eb0efe5063bb10bcb653e4f8e92a74719c03a347 ]
The data fork scrubber calls filemap_write_and_wait to flush dirty pages
and delalloc reservations out to disk prior to checking the data fork's
extent mappings. Unfortunately, this means that scrub can consume the
EIO/ENOSPC errors that would otherwise have stayed around in the address
space until (we hope) the writer application calls fsync to persist data
and collect errors. The end result is that programs that wrote to a
file might never see the error code and proceed as if nothing were
wrong.
xfs_scrub is not in a position to notify file writers about the
writeback failure, and it's only here to check metadata, not file
contents. Therefore, if writeback fails, we should stuff the error code
back into the address space so that an fsync by the writer application
can pick that up.

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.
