[ Upstream commit2c0468e054] Without FEC, dm-verity won't call verity_handle_err() when I/O fails, but with FEC enabled, it currently does even if an I/O error has occurred. If there is an I/O error and FEC correction fails, return the error instead of calling verity_handle_err() again.

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.
