Darrick J. Wong 3628a1a384 xfs: mark data structures corrupt on EIO and ENODATA 
[ Upstream commit f39854a3fb ]

I learned a few things this year: first, blk_status_to_errno can return
ENODATA for critical media errors; and second, the scrub code doesn't
mark data structures as corrupt on ENODATA or EIO.

Currently, scrub failing to capture these errors isn't all that
impactful -- the checking code will exit to userspace with EIO/ENODATA,
and xfs_scrub will log a complaint and exit with nonzero status.  Most
people treat fsck tools failing as a sign that the fs is corrupt, but
online fsck should mark the metadata bad and keep moving.

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 reStructuredText 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.
